Question

$\displaystyle \sf \red{ \int_{0}^{ \pi} \frac{2 {x}^{3} - 3 \pi {x}^{2} }{(1 + sin \: x) {}^{2}} \: dx}$​

Answer 1

Step-by-step explanation:

I don't know the whole answer , but I think you should us the property

In place of x , put (a+b-x)

So Put (π-x) in place of x

So 2(π-x)³ - 3π(π-x)²/(1+sin(π-x))²

Sin(π-x) = sinx
