Yo trigonometry, let's kick it!

 

Sine, Cosine, Tangent,

Sine, Cosine, Tangent

 

All right stop, let’s calculate and listen

Rach is back with a real cool invention

Trig- it grabs a hold of me tightly

Got all the angles of Keira Knightley

What’s it used for? Yo, You wanna know

Makin architecture and reading ocean flow

Got yourself three sides, and a right angle

SOHCAHTOA gonna bust that triangle

 

SINE, it’s gonna blow your mind

An angle, a side, and a line you gotta find

O! Is for the opposite line,

Directly across from the angle, they align

Hypotenuse goes under the divide,

Cancel with the inverse, do it on both sides

 

Inverse sin times the ratio, solve it

On to the next concept let’s evolve it

 

Sine, Cosine, Tangent,

Sine, Cosine, Tangent,

Sine, Cosine, Tangent,

Sine, Cosine, Tangent

 

Now that we got that strong

Time for COSINE, yo it won’t take long

First you find the line where the measure is vacant

From the given angle - hypotenuse/ adjacent

A over H equals COS times the angle,

Inverse them both so you can wrangle

Solve it like before, there ain’t no excuse

Cosine, Adjacent, over ‘potonuse

 

Rollin' in my 4.0

Learning all this trig is gonna make me dough,

Help with SAT, that’s important to me

Should we stop? No, we’re on to concept three

Let’s figure out, T-O-A tangent

That ratio’s gonna be opposite adjacent

Now we’re on to the main occasion;

The next step is using it in an equation  

 

Triangle has a side undetermined

Opposite adjacent from the angle that’s certain

Set it up, tan of angle on one side

Opposite divided by adjacent, then multiply

Inverse, that’s 1 over TAN

Multiply it left and right, yeah that’s the plan

Now you’re gonna find that X is isolated

Simplify your answer, send it off to be graded

 

Inverse, is all that’s left to be done

Taking’ your ratio, all under one,

Switch-in it up, to find the angle this time

You’re gonna use this one when all you have is lines

Now we can deduce

How we’re gonna use

Inverse sin of opposite over ‘potenuse

 

It equals the angle, yo, I'll solve it

Replace with the ratio you need to resolve it

 

Sine, Cosine, Tangent, (and inverse)

Sine, Cosine, Tangent, (and inverse)

Sine, Cosine, Tangent, (and inverse)

Sine, Cosine, Tangent, (and inverse)

​

Yo, man, let's get out of here! Word to your teacher!

 

Sine, Cosine, Tangent, Sine, Cosine, Tangent

Sine, Cosine, Tangent, Sine, Cosine, Tangent
