Question

Find the amplitude and period of f(x)=-5sin(5x-2).

Answer 1

\[\large\rm y=Asin (Bx-C )+D \]
original equation where \[\left| A \right|\] is amplitude
and \[ \frac{ 2\pi }{ \left| B \right| }\] period
and D is vertical shift C is horizontal or phase shift

Answer 2

Okay so 5 is the amp and 2pi/5 is period.

Answer 3

How do I find this for a cosine function?

Answer 4

2pi is full cycle if given is degree then u should put 360
and yes that's correct

Answer 5

same formula for cosine function

Answer 6

Okay, thank you very much :)
