Question 1021928: What is the amplitude,period, vertical translation and phase shift of this: 4cos(x/3-pi/3)

You can put this solution on YOUR website! What is the amplitude,period, vertical translation and phase shift of this:
4cos(x/3-pi/3)
======
Form:: y = a*cos(b(x-c)+d
Your Problem::
y = 4*cos((1/3)(x-pi)+ 0
----
amp = |a| = 4
period = (2pi/b) = (2pi/(1/3)) = 6pi
vertical trans = d = 0
phase shift = c/b = pi/(1/3) = 3pi
