Transcript of Trigonometry Poem

Trigonometry! Trigonometry looks quite challenging
But it really is fairly easy You start out pretty shaky
But you'll get it in time, believe me It mainly involves triangles
And their angles and their sides Still feeling confused?
Just follow this simple guide! Sine, Cosine, and Tangent
Is where we always begin Memorize your identities
And you will surely win SOHCAHTOA is what I use
to remember hypotenuse, opposite, and adjacent Using this on a test or quiz
Will help you get the highest percent Opposite over hypotenuse is Sine
It isn't too hard to find Adjacent over hypotenuse is Cosine
It's a breeze, just follow the lines Adjacent Hypotenuse Opposite Hypotenuse Opposite over adjacent is Tangent
It's so simple that you won't even need a hint Opposite Adjacent For Cosecant, Secant, and Cotangent
Just flip the functions upside down Once you master this simple trick,
there's no need to frown Cosecant is the opposite of Sine
Hypotenuse over opposite is how it's defined Hypotenuse Opposite Secant is the opposite of Cosine
Hypotenuse over adjacent when you flip it this time Hypotenuse Adjacent Cotangent is the opposite of Tangent
Adjacent over opposite is what you'll get Adjacent Opposite The angles of a triangle add up to 180 degrees
These facts about triangles are all that you need A + B + C = 180° Circles and angles are next on the list
Follow our lead and you'll get the gist On your pie circle you will rely
One complete rotation is 2 pi We made the pi circles with Mrs. Grogg's help
Now there's no need to worry or yelp The initial side of an angle is the starting position
The terminal side is the position after rotation The endpoint of the ray is the vertex
Coterminal means the same initial and terminal sides

Let's see whats next! A central angle called a radian
is the same length as the radius The measure of an angle is determined
by the amount of rotation from start to end We use degrees to measure
the amount of rotation all together With this knowledge we have stated
You're sure to be the greatest Just keep your head held high
And when it comes to Trig, reach for the sky!
