# Math Help - Integration - Reduction Method

1. ## Integration - Reduction Method

Hi

I've been unable to get the evaluation part of the question correct. Could someone please show me where i got it wrong pleaaaaaaaaase???

2. You just forgot the coefficient $n(n-1)$ when $n=2$

It should be ( in the second line)

$-2 + 12 \left [\frac{e^{2x}\cos(x)(2\cos(x) + 2\sin(x))}{8}\right ]_0^{\frac{\pi}{2}} + \frac{3}{2} \cdot (2)(2-1) I_0$
