Evaluate the foll

Answer :


We will use integration by parts.


Here, take f(x) = x2 and g(x) = sin x


f’(x) = 2x

Substituting these values, we evaluate the integral.


We use integration by parts again.

Here, take f(x) = x and g(x) = cos x


f’(x) = 1

Using these values in equation for I1

Substituting I1 in I, we get

I = (0 + π + 0) – (2)

I = π – 2
