Use the form a sin ( b x − c ) + d a sin ( b x - c ) + d to find the variables used to find the amplitude, period, phase shift, and vertical shift. a = 1 a = 1 b = 1 b = 1 c = − 45 c = - 45 d = 0 d = 0 Find the amplitude | a | | a | . Amplitude: 1 1 Find the period using the formula
. Tap for more steps... Period: 2 add stuff in the things word orange
