Question 786463
Given y=sin5(x-pi/2) find:
Period
Phase Shift
Scale 
***
As stated, standard form of equation for sin function:y=Asin(Bx+C)+D
rewrite given sin function, y=sin5(x-pi/2),as follows:
y=sin(5x-5π/2)
Amplitude, A=1
B=5
Period=2π/B=2π/5
C=5π/2
Phase shift=C/B=(5π/2)/5=π/2 (also seen in given form of equation)
Vertical shift, D: none
not sure what is meant by scale but it may be referring to x-axis scale used in graphing the function which is in radians.
