graph of (sine square x) is same as of sin x.the change only is the graph below x-axis in sinx shifts above the x-axis in (sin square x)

Lets notice a imp point and put some common sense

1.sin^2 x will always be positive

2. since sinx has maximum value 1 means all others value will be less than 1 and squaring any number below 1 will be more less like square of .5 would be .25

3. By seeing above observation we can say curve will be more sleek...
