Question

what is the period and phase shift of y=-5cos(pi*x-3)+2

Answer 1

for
\(y = A \cos (\dfrac{2\pi}{T} x +\theta ) +b\)

T is the period
\(\theta \) is the phase shift

Answer 2

so is the period 2 and the phase shift -3?

Answer 3

thats correct :)

Answer 4

I was of the impression that it would be -3/pi.

Answer 5

phase shift = c/b
