State the amplitude, period, and phase shift (if possible) of y=-3cot(4x-2π).

Question

I know that there is no amplitude but I am not sure about the phase shift or how to find the period.

Answer 1

There actually is an amplitude, the value is 3 (the value in front of the cot)

For the period and phase shift, this is not written in standard form. Need to do that first.

y=-3cot(4(x-π/2))

Period = π/B = π/4

Phase shift = π/2 to the right (right due to the subtraction sign)
