Question 181095
Find the amplitude, the period, and the phase shift for the given equation.For any fractions, enter as 'a/b' with no spaces. 
y = 7*sin(5x - Pi/2)
---------------
Amplitude = -7 to +7 peak to peak.
The period is 2pi/5 radians.
The phase shift is pi/2 to the right (on the graph), or pi/2 to the right.
