Amplitude and period (1 Viewer)

[BlueGas]

I know that the amplitude is the number infront of the function, but how do I find the period?

 

[photastic]

T = 2pi/b where b is the coefficient in front of x or whatever the pronumeral is.

Didn't your teacher teach you this?

I've never been taught this in my life.

And also the period for tan functions are

pi/b where b is whatever pho just said

It is a little small section in MIF at the bottom of the page whereas it is in clear blue box in Cambridge.

Yes I already know this after my own study.

Still doesn't change the fact I was never taught. Was just showing drongoski that no some people don't get taught everything.

So for sin and cos functions it's 2pi/b but for tan function it's pi/b?

Yes.

Some teachers just don't have commitment. Teacher told entire class to finish all the topics (at this point, the teacher hasn't even started rates/finance) so the class started rushing and studying it. Turns out in the exam, she removed the Rates/Finance questions.

Yes.

Simple, thanks!
