Download audio file (Integers_yessur.mp3)

Chorus:

life aint as simple as one and one is two

gotta talk about negatives wichu

integers include the entire bunch

in Latin that means “whole” or “untouched”

whole numbers and their negatives

are all called integers kid

zero are part of integers, I aint lyin’

first ones to know this were the Mayans

was a place holder in their calendars

of a base 20 system, not 10 like ours

probably ‘cuz they didn’t just count on their hands

also on their toes in that Chiapas land

southernmost part of Mexico

round 36 B.C. wrote the first zero

by 628 had it in India

written in a book by Brahmagupta

world won’t end in 2012 so don’t be scared

starts a new baktun of bout 400 years

this ain’t no show like gigante

breakin’ it down like Jaime Escalante

start with number line in both directions, yo

positives on the right, increase as they go

negatives on the left, don’t get messed up

value becomes less as numbers go up

Chorus

to add, go right from the starting point

to subtract go left from the starting point

answer is on the number that you land

can do it another way, yes you can

adding a negative is an easy situation

change to positive while changing to subtraction

subtract a negative, gotta do the same

switch to addition and to positive you change

for example take 18+(-7)

answer you get gonna be 11

or if you take 30-(-10)

40 is your answer my friend

or try 4+(-8) know what you get

-4 will be your answer, that’s a sure bet

if you got 4 and lose 8 you down a few bro

you owe four and that’s less than zero

Chorus

multiply and divide gotta know something

couple rules now while that beat is pumpin’

signs are same answer is positive

signs are different answer is negative

a negative times a positive is a negative

a positive times a negative is a negative

a positive times a positive is a positive

a negative times a negative is a positive

divide is the same rule as multiplyin’

that’s all there is to integers, stop ya cryin’

add, subtract, multiply or divide

it’s all good man, give it a try

-9 times 4, don’t need no tricks

signs are different so you get -36

-3 times -5 gives ya +15

‘cuz signs are the same, u know what I mean

-40 divided by 8

answer is -5, aint that great

54 divided by -6 equals -9

gon’ be negative each an every time

Circulatory System Rap | Ur Blood, Brother

Chorus

system’s called circulatory

nourishing cells is the gist of this story

heart pumps blood, takes oxygen we breathe

with nutrients to the cell it feeds

similar cells come together to form tissues

different tissues join so you won’t have any issues

organs work together to maintain life function

gonna rhyme about a system at this juncture

how do you transport nutrients to the cell

or take away waste, this I’m gonna tell

fluid transports smooth so that there’s no flood

it’s the circulatory system, uses a tissue called blood

blood’s make of plasma which is mostly water aight

suspends 2 types of cells, red blood cells and white

RBC’s contain hemoglobin carries O₂

to every cell that make up me and you

Chorus

white blood cells defend us, could be a phagocyte

eats them germs attacked by lymphocytes

lymphocytes produce antibodies that surround

bacteria or a virus, phagocyte gulps ‘em down

3 kinds of blood vessels so flow is maintained

capillaries arteries and veins

veins take blood to the heart, arteries away

if you can’t remember this think away = “a”

capillaries are microscopic, thickness of one cell

branch from arteries, keeps your tissues well

brings O₂ and nutrients, takes away waste

CO₂ released once O₂ is displaced

process is called blood oxygenation

happens to every human from every nation

reason why we need to breathe all the time cant you see

aerobic organisms use it for energy

Chorus

blood flows through the veins and on to the heart

a 4 chambered pump, it’s the most important part

blood enters right atrium from the vena cava

flows into right ventricle just like lava

right ventricle pumps to the lungs blood goes

gets more O₂ then back to the heart it flows

through left atrium to the most muscular part

left ventricle pumps oxygenated blood to all your body parts

through the aorta a blood vessel baller

the largest artery then branches into smaller

down to capillaries drops off O₂ you see

cycle then repeats automatically

now you know the function of your blood and your heart

it’s so beautiful, not a science but an art

stay healthy, heart disease is killer #1

eat lots of raw veggies and exercise, son

PEMDAS Rap | P to the E to the M to the D to the A to the S

Chorus:

if you see a long mathematical expression man

simplify it by combining what you can

makes it much easier, don’t make me stutter

PEMDAS makes math smooth like butter

first is the P, means Parentheses

go inside those curved lines, believe me

do all the math you find in them

rewrite the expression now my friend

E for Exponents in the second phase

those little numbers you see that are raised

for example if you have 3 to the second power

make it a 9 real fast, don’t take an hour

third is M for Multiplication

in an expression or an equation

simplify by timesin’ what you see

and if no operation next to parentheses

Chorus

D is for Divide, order number four

divide could be a slash or maybe something more

a line in a fraction that can be simplified

or two dots above and below a straight line

Addition is the operation second to last

almost done with PEMDAS so that test you can pass

add the numbers with addition signs between ‘em son

should have no other operations left but one

number six is Subtraction, that’s the S

look for tiny horizontal line, don’t guess

difference between two numbers, just about done

take away amount on right from the left one

Chorus

if you forget PEMDAS don’t sweat it

remember this phrase that’ll help you get it

Please Excuse My Dear Aunt Sally

it’s in every classroom from NYC to Cali

Pi Rap | Don’t Let Pi Make Ya Cry

Chorus:

take all the points equidistant

from one center and in an instant

you have a shape that very familiar

a circle is round and well, it’s circular

parts are real easy, a few you need to know

radius is length of center to outside, yo

double radius and you’ve got diameter

goes from one side straight to the other

take the outside and go all the way around

length is circumference, like a king’s crown

go around a wheel, my bling, or anything that’s round

see circumference everywhere, don’t be no clown

special number you also need to know called π

mathematical constant, same everywhere, why

divide circumference by diameter, this is pretty fly

always get 3.14 no matter circle’s size

Chorus

Egyptians were the first to discover pi

used it to build the pyramids so high

tallest manmade structures in the world, believe me

for nearly 4,000 years until 1311 A.D.

let’s say circumference is C, diameter d

then C=πd, aint this easy

if radius is r then C is 2πr

Since d is double r, now we’re goin really far

let’s try an example with Dayton 22’s

22 inches in diameter you use

use C=πd on that sweet ride

length around that rim is 69.115

Chorus

what if you want to know the size of some bling

droppin a G per sq inch of that round thing

need to know the area to figure out the cost

A=πr², now you the boss

times the radius by itself then pi

radius is 3 inches, 3² is 9

wastin your dollars, instead you could buy a car

price of that piece is more than 28 large

when your ridin’ on your Ds and you got a mad thirst

is a soda can enough, gotta know sumthin’ first

can is a cylinder, top is a circle aight

find area then multiply by height

Chorus

find volume of how much the can can fill

it’s V=πr²h, now you can chill

until you get to the basketball game

see that sphere get taken to the hole by LeBron James

rules say make C 29.5 inches dude

can you find the volume if it’s 4/3πr³

any circumference equals 2πr

told you this is true no matter where you are

divide each side by 2 and get 14.75

then by π and r equals 4.695

plug that in to 4/3πr³ fo sho

volume in cubic inches is about 434

atom is the basic unit of matter and

all things alive or not are made of ’em

they’re what you get when you breakdown anything

so that in the universe everything is everything

made up of 3 different parts

at the center is the nucleus, it’s the heart

Inside are protons, positively charged

each one of those Ps wants to live large

gotta be stuck together by a neutron you see

no charge, got the nuclear strong force G

if it weren’t for these guys, atoms be buggin’

and then there’d be no matter, there wouldn’t be nothin’

outside the nucleus is the third part

but don’t think it’s the end, it’s only the start

electrons are negative, attracted to the Ps

opposites attract in all of chemistry

inside the atom, protons call the shots

number of protons you have, tells ya the element ya got

need one neutron for every P

but as elements get heavy, more neutrons ya need

Uranium 235, 92 protons

subtract and get 143 neutrons

repelling protons, unstable dude

143 neutrons aint enough glue

neutron from outside hits it like a bullet

two smaller atoms form, 3 neutrons, that’s not it

chain reaction, nuclear fission comes alive

lots of neutrons slam U-235

Chorus:

parts of the whole lose mass, so somthin’ is missin’

must be binding energy, Einstein was guessin

he turned out to be right so don’t be scared

mass converts to energy cuz E=mc²

nuclear energy is mighty strong

when released, lasts really long

c is the speed of light you see

square it and you get 9 with 16 zeros B

that small change in mass you times it by

to get lots of energy as heat, that aint no lie

put it in a bomb, destroy a city

or power a plant to make electricity

Chorus:

negative b plus or minus the square root

of b squared minus 4ac all over 2a

negative b plus or minus the square root

of b squared minus 4ac all over 2a

an equation with a variable of x

exponent of 1 and 2, don’t mean to vex

and a whole number is a quadratic

recognizing this gonna be automatic

start with ax^2 + bx + c = 0 please

coefficients are ez as you’re a,b,c’s

how to solve for x is ez too bro

if ya follow the formula, just follow my flow

Chorus

x^2 + 5x -6 = 0

take this quadratic’s coefficients fo’ sho

a is 1 b is 5 and c -6

for the erratic quadratic Rhyme ‘n Learn master mix

-5 plus or minus the square root

of 5^2 minus 4 times 1 times -6 dude

all over 2 times 1, this ain’t no trick

the solutions are 1 and -6

Chorus

2x + 1 = -x^2 yo

that ‘s x^2 + 2x +1 = 0

plug that sucka into the quadratic form

-2 plus or minus the square root of 2^2 minus 4

times 1 times 1 and you’re almost done

all over 2 times 1 son

will give you not two answers but one

simplify it all to get -1

Angles Rap | Gotcha Angles Covered

venhi — Mon, 27 Dec 2010 18:16:56 +0000

Download audio file (Gotcha_Angles_Covered.mp3)

Chorus:

gonna talk about angles and lines if you please

unit of an angle is a degree

not the degree that makes you hot or cold

this aint temperature, ain’t even close

start with two lines in this joint

converge at the vertex, or an endpoint

the point I’m tryin’ to make with this rhyme, it’s not

it’s a geometric point, looks like a dot

angulus means corner in Latin

ankylos means crooked in Greek if you’re rappin’

corners everywhere, 90 degree angles

listen up now, so with angles you can tangle

one line drawn straight up, makes an angle right

in Latin it’s rectus, in English that’s upright

word borrowed from the Romans, ya see

Julius Caesar was a G until 44 BC

Chorus

draw a line inside an angle of 90 degrees

now you got two angles called complementary

for example if you got an angle of 33

its complementary is 57, B

if you open angle wider, double the size

to you might look like a straight line

there’s still a vertex as you can see

got yourself an angle of 180 degrees

if you cut this angle of 180

now you got two called supplementary

for example if you got an angle of 120

supplementary is 60, money

Chorus

vertical angles formed by intersecting lines

easy way to find ‘em all each and every time

opposite ones are equal to each other

that’s the truth kid, even ask your mother

for example if one angle is 70

find vertical angle x, man that’s easy

x is 70 and other two you can find

supplementary angle on other side of the line

that means other two are 110

supplementary angles equal 180 and

opposites are the same, now you know it all

now let’s talk about an angle that’s really small

small is a cute little angle now

acute angles are less than 90 degrees, wow

fat angles are obese or obtuse

greater than 90, that angle got some juice

wanna intersect parallel lines, don’t hit the floor

2 sets of vertical angles turn into 4

same exact angles are formed below

don’t let these corresponding angles make ya slow

all you need to know about angles there it is

so you can pass that math quiz

if you get stuck and need to discover

listen to my rhyme to have all the angles covered

Chorus

Pythagorean Theorem Rap | RtAngles Rhyme

Chorus:

90 degrees make up a right angle

corner of a square or a rectangle

forms a type of triangle that’s right

gonna rhyme about this with all my might

gonna rhyme about triangles if you don’t mind

in total there are a few different kinds

isosceles: 2 sides are the same

scalene: 3 unequal of a frame

one special shape is everywhere though

look in a corner, right triangle bro

3 angles, one of which is 90 degrees

understand this and you’ll hold all the keys sides are called two legs and hypotenuse

hypotenuse gives the right angle juice

from the right angle on the opposite side

as the longest side it’s got a lot of pride

Chorus

other angles smaller than 90 degrees

all add up to 180 don’t you see

leg can be opposite or adjacent

solve trig problems, don’t be complacent

need to use sine, cosine and tangent

properties of an angle, understand it

if not don’t worry too much

just use SOHCAHTOA to get you through the clutch

sine is opposite over hypotenuse

cosine is adjacent over hypotenuse

tangent is opposite over adjacent

right angle expert now you can represent

Chorus

with a calculator and limited info

you can figure out sides and angles bro

the way to measure ‘em when you see ‘em

formula called the Pythagorean theorem

let’s say hypotenuse is “c”

and the legs are “a” and “b”

in every right triangle everywhere

a² + b² = c²

Pythagoras was an old school G

in Greece he lived around 500 BC

wrote the first proof to the theorem

beat India to it and the Babylonians

Chorus

let’s say you gotta build a ramp 3 feet tall

start it four feet from the wall

will let you know how much wood you need

shred that baby at just the right speed

just plug in 3 and 4

into the Pythagorean theorem, nothing more

take the square root of 25

length is five, now skate and stay alive

if a plane takes off at 40 degrees

how high is it if it travels 2000 feet

use SOHCAHTOA to find opposite

sine of 40 times 2000, that’s it

Chorus

suppose you need to find a side

hypotenuse is 13, other is 5

find the missing leg by yourselves

Pythagorean theorem says that it’s 12

cruisin’ down the highway in your Bentley

going in a straight line, feelin’ like a G

checkin’ out your speed, set at 63

can also use a graph to calculate velocity

say x-axis is time and y is position

velocity easy to get, don’t you listen

just find change of y over change of x

slope is rise over run or m…that’s a bet

don’t know what I mean, review on my mic

a linear function is like that cruise down the pike

start at b, where time is zero money

y=mx+b, don’t laugh, this ain’t funny

Chorus:

we ain’t drivin’ in a straight line on our next trip

slowin down speeding up as you zip

velocity is changing, with acceleration bro

need to use calculus to find out all the info

non-linear functions are mad confusing

this ain’t no simple graph like y=mx+b

in a linear function, or a straight line

slope is constant each and every time

but we aint drivin’ in a straight line on our next trip

slowin’ down speeding up as you zip

velocity is changing with acceleration bro

need to use calculus to find out all the info

crazy lookin graph with all them curves

slope is always changing, that’s my word

gotta calculate the derivative

at any point on the line, need to find what it is

Chorus

y always relates to x as a function

also called f(x) at this juncture

pick any point on the curve at x

y coordinate will be f(x)

pick another point along the way, yessur

tiny distance h from where you were

that x coordinate’s gonna be x+h

y will be f(x+h)

slope is change in y over change in x

m=f(x+h)-f(x)

over (x+h)-x

almost done now and you’ll be set

Chorus

that’s numerator over h bro

but now we gotta make that tiny h zero

can’t have a zero in denom so here’s what we do

find limit as h approaches zero dude

it ain’t really hard, think more, don’t complain

calc is the study of instantaneous rate of change

accurate measurements are infinitesimally small

listen to my rhyme, ya ‘bout to know it all

for finding slope now need a derivative

can find it at any point with the function they give

f(x) = x², piece of cake

to find derivative just plug in for pete’s sake

derivative is dy/dx or f’(x)

same thing, none is better than the rest

that’s (x+h)² – x² over h

equals x² + 2xh

+ h² – x² over h

equals 2x+h ya see

but h is approachin’ zero, whatd’a think G

derivative of x² is 2x finally

how do you write a number really big

without tiring out your hand, ya dig

say it’s a trillion that’s 1 and 12 zeros

1 million million, I aint writin that out bro

easy way to do it everyone from every nation

uses it, it’s called Scientific Notation

let’s start with a number like 110

look for the decimal, it’s at the end

move the decimal to the left a certain number of spaces

until there’s one space left, that’s two places

now you got 1.10 not done yet

add a x 10 with an exponent

exponents gonna be number of places you moved

in this case that’s gonna be two

now you got 1.10 x 10²

drop off the zero, make it easier to write dude

yeah that Scientific Notation, call it SyNote

got about 100,000,000,000,000 cells in the human body

or 1.0 x 10¹⁴

sun is 92,955,807 miles away

write in SyNote, make it easier to say

find the decimal, move it to the left

that’s seven places, till there’s one left

round the decimal to 9.3 cuz it’s easier than

writing out 9.2955807

use SyNote so it doesn’t take an hour

9.3 x 10⁷

SyNote also used for really tiny numbers

so writing them out doesn’t take the rest of the summer

virus of the common cold

is 0.00000003 meters bro

move the decimal to the right this time

8 places come on man don’t be blind

got 3.0 x 10^-8

easier to write now man SyNote is great

in your computer you got a processor with

a width of 0.000000065 m, or 6.5 x 10^-8

you’re using it right now

sign of the exponent easy to remember

simple rule to use beginning this September

large number sign is positive

small number sign is negative

SyNote uses x 10 with an exponent

as an easy way to rewrite is what I meant

whether big or small it’s for amounts that are extreme

check all your work, keep the math clean

population of US is 3 x 10⁸

fraction of the world can you estimate

total is about 7 x 10⁹ dude

first 7 divided by three is about 2

divide the exponents by subtracting

9 minus 8 is 1 is exactly

that’s how you do it to get 10¹

now you got 2 x 10 or 20 son

one human chromosome contains about

220,000,000 base pairs, or 2.2 x 10⁸

an E.coli bacteria is 0.000002 m long, or 2.0 x 10^-6

the distance to Mars is 78,000,000,000 m

or 7.8 x 10¹⁰

for numbers that are really large, or small

gotta use that SyNote
