Question

Hey, I am graphing a Sin graph and I just want some help with the Phase Shift section. The initial graph problem is 2sin(4x+pi/2)-3. I believe the formula for the Phase Shift is -c/b so I did -pi/2/4. This gives me a compound fraction and I am confused as to where to go from here.

Answer 1

phase shift = -c/b

phase shift = -(pi/2)/(4)

phase shift = -(pi/2)/(4/1)

phase shift = -(pi/2)*(1/4)

phase shift = -(pi*1)/(2*4)

phase shift = -pi/8

Answer 2

thank you for the help!
