We know that fom -1 to 0 , x is negative and sin(piex) is also negative so fom -1 to 0 the given function is x.sin(piex)
Also fom 0 to 1 , x and sinpiex are both positive so the function is x.sin(piex)
zNow in case of limits 1 to 3/2 , x is positive but sinpiex lies in the third quadrant (pie , 3pie/2) , so the function is taken as -x.sinpiex
Now the given function can be integrated using by parts .
