y=2cos(x-pi/12. What is amplitude, period, vertical shift, and phase shift?
***
Form of equation for cos function: y=Acos(Bx-C)+D, A=amplitude, period=2π/B, phase shift=C/B, vertical shift=D
For given cos function: y=2cos(x-pi/12)
Amplitude=2
B=1
period=2π/B=2π
C=π/12
Phase shift=C/B=(π/12)/1=π/12 (shift to the right)
vertical shift: none
