GRAPHS OF |sinx| and (sinx) square

UR QUES, OUR SOL: 1

Q. What is the difference between the curves of |sinx| and (sinx) sq.    ( DC/ M)

(asked by RAVI JHA)

SOL: The curve of y = |sinx| can easily be drawn from the sinx as the portion of the curve below x- axis will get inverted.

For the y =(sinx) sq, we can write it as (1-cos(2x))/ 2 , which we can easily plot by plotting cos2x, then inverting and halving it so as to get -cos2x/2 and later shifting the origin, we will get the shape of   

y= (sinx) sq
