**Reiny**, Monday, August 4, 2014 at 10:23pmrewrite it in the more general form as

y = (1/4) cos 3(x + 7/3)

compared to y = a cos k(Ø + p)

the amplitude is 1/4

the period is 2π/3

the phase shift is 7/3 to the left

for your equation in the original form a common mistake would be to state that the sphase shift is 7.

Note the step I took to avoid that error.
