Professor Burger shows you how to use all of the tools at your disposal to effectively graph complicated trigonometric functions involving sine and cosine. He will show you how to recognize changes in period, amplitude, and vertical and phase shifts in the equation and how to correctly incorporate them into your trig function graph. He will also show you a three-step process of translating the equation, graphing the intermediate steps, and finailzing the graph. The examples you will use are y = -2sin(x- Pi/4)+1 and y = 2cos(Pi*x)-2. These equations both involve complications like those listed above (as indicated by their added constants and coefficients).

Taught by Professor Edward Burger, this lesson was selected from a broader, comprehensive course, Precalculus.

Trigonometry, motherfuckers. Graph the SHIT out of those Sine fictions. Kick that unit circle right in the cunt.

LOVE how it cuts off!

[schueboo]

i sorta get it lol

[jubjub444]

i still dont get this crap, i even asked a math teacher of how a period converts and they didn't know...

[gujuman2394]

haha i got the last laugh.. all i was confused was with the phase shift.

[DjDrfreeman]

"shifty business" i see whatcha did there -_-

"I finally get it" - video cuts out "im so lost now :( "

lmfao

@utubeviewer90 that's a cosine graph!

This was more helpful than my teacher.
