Find a cosine and sine function whose graph has amplitude "pi/5" and B=2
***
Basic form of equation of sin function: y=Asin(Bx-C)+D, A=amplitude, Period=2π/B, Phase shift=C/B, D=Vertical shift
Basic form of equation of cos function: y=Acos(Bx-C)+D, A=amplitude, Period=2π/B, Phase shift=C/B, D=Vertical shift
...
For given problem: (assume no phase shift or vertical shift)
sin function: y=(π/5) sin(2x)
cos function: y=(π/5) cos(2x)
