WebTrigonometry Examples Popular Problems Trigonometry Find Amplitude, Period, and Phase Shift f (x)=2sin (3x) f (x) = 2sin(3x) f ( x) = 2 sin ( 3 x) Use the form asin(bx−c)+ d a sin ( b x - c) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a = 2 a = 2 b = 3 b = 3 c = 0 c = 0 d = 0 d = 0 WebIf you simply divide both sides by cos 2 x then the problem will be really easy to solve for you. sin 2 ( x) = 3 cos 2 ( x) sin 2 ( x) cos 2 ( x) = 3 tan 2 x = 3 tan x = ± 3. From the last step, you can just arctan both sides twice, once with 3 and another with − 3 and you will have both of your answers. Share.
