MCQ
$\int_{ - 3}^3 {\frac{{{x^2}\sin 2x}}{{{x^2} + 1}}\,dx = } $
  • $0$
  • B
    $1$
  • C
    $2{\log _e}3$
  • D
    None of these

Answer

Correct option: A.
$0$
a
(a) Obviously the function $\frac{{{x^2}\sin 2x}}{{{x^2} + 1}}$ is odd, 

so $\int_{ - 3}^3 {\frac{{{x^2}\sin 2x}}{{{x^2} + 1}}\,} dx = 0$.
