Give the following amplitude and the period of each of the following: (a) y=1/2sin3x (b) y=3cos1/2x
***
Equation for sin function: y=Asin(Bx-C), A=ampiltude, period=2π/B
For: (a) y=1/2sin3x
B=3
Period: 2π/B=2π/3
Amplitude=1/2
..
Equation for cos function: y=Acos(Bx-C), A=amplitude, period=2π/B
For: b) y=3cos1/2x
B=1/2
Period: 2π/B=2π/(1/2)=4π
Amplitude=3
