The question asks me to integrate x^2 sin x dx and then use it to find the exact value of the integration of abs ( x^2 sin x dx) with upper limit of pi/2 and lower limit of -pi/2.
I have found the integration of x^2 sin x dx which is -x^2 cosx + 2xsinX + 2 cosx + C
but after putting in the upper limits and lower limits i get the answer 2pi, where have i gone wrong because my first part is correct but the second part is different from the answer given.
