  2. B \(\pi / 2\)
  3. C \(0\)
  4. D \(-\pi\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(0\)

Step-by-step Solution

Detailed explanation

Let \(\begin{aligned} I & =\int_0^{2 \pi} \sin ^6 x \cos ^5 x d x \\ I & =2 \int_0^\pi \sin ^6 x \cos ^5 x d x\end{aligned}\) \([\because f(2 \pi-x)=f(x)]\) Let \(f(x)=\sin ^6 x \cos ^5 x\) \([\because f(\pi-x)=-f(x)]\)…
