Question 644238
State the amplitude, period, and phase shift of the function y=-2sin(4theta+2pi).?
**
Equation for sin function: y=Asin(Bx-C), A=amplitude, Period=2π/B, Phase shift=C/B
For given sin function: 
y=-2sin(4x+2π)
Amplitude=2
B=4
Period=2π/B=2π/4=π/2
C=2π
Phase shift=2π/4=π/2 (shift to the left)
