You can put this solution on YOUR website! Graph the function y=cos(theta-pi) and state the phase shift,amplitude, and period
***
Equation for cos function: y=Acos(Bx-C), A=Amplitude, Period=2π/B, C/B=Phase shift
For given function: y=cos(x-π)
Amplitude=1
B=1
Period=2π/B=2π
C=π
Phase shift:C/B=π/1=π(shift to the right)
See graph below:
