1. The problem statement, all variables and given/known data

3. The attempt at a solution

Hello people, i have had a little problem solving this graph. It looks really easy, but im still couldnt solve it ?!

a x Sin (bx + c) + d

a = amplitude

b = period

c = phase shift

d = vertical shift

thx in advances.

Edit:

I have solved the equation for the Sine ( thank you folks )

Equation for Sine:

2 sin(1(x-2))

Trying to find the equation for Cosine:
