Question

How to find amplitude and period from equation?

Answer 1

If your graph is a COS or SIN graph :


`y = a \sin(bx) + c`
a is the Amplitude
and period is:

`(360)/(b)`

If your graph is a TAN graph :

`y = a \tan(bx) + c`
A TAN graph has no amplitude as it has no Maximum or Minimum value.
To find period :

`(180)/(b)`
