I have to find the amplitude, period, phase sfit, and vertical displacement but I am not to good at thos so I was wondering if you can tell me if I am doing it correctley thanks! :)

everything seems in order except the period

you said it was 2pi/5 or 360/85....it should be 360/5 degrees, which is 72 degrees. But that seems like you made an honest mistake and meant to type 360/5.

also, 85 degrees is 17pi/36 radians, why did you put the minus sign in front?

otherwise, good job! :) - Apr 12th 2007, 06:39 PMjustinthanks!
Jhevon thank you I did not realized I put the minus

thank you! :)
