     Identify the following curves by their formula   
  
  Solution
1. Looks like sin(x) curve becase it is oscillating with period: 2PI and starts with y=0 at x=0
So, y=sin(x)
2. Again sinusoidal curve starting with y=0 at x=0. But period is not PI instead of 2PI
Note for a function:y=sin(Ax) the period is:2PI/A
HEnce, here, A=2
SO the function is:
y=sin(2x)
