Equation: y= a sin (bx+c) =d
y= a cos (bx +c) +d
amplitude: IaI
period: 2pi/IbI
frequency: IbI/2pi
phase shift: - c/IbI
vertical shift: d

Example: y = 2sin (5x + pi/4)
First the easiest to find is the amplitude which is a. The a in this equation is 2, so the amplitude is 2.
Then find the frequency which is 5/2pi
Then find the period which is opposite of ^
Then the phase shift is -pi/20
Find these by using the equations above:)
