Help with $\\int_0^{\\pi 2} \\frac{x \\cos(x)}{\\sin^2(x) + 1 . . .
Then, plug it into (1) to obtain $$\int_0^{\frac{\pi}{2}} \frac{x \cos x}{\sin^2x+1}dx = \frac{\pi^2}8-I=\frac12[\sinh^{-1}(1)]^2$$
Solve ∫ (from 0 to frac{ pi) of { 2}}{left(cos(x)right)}^frac{1{2}}sin . . .
The answer is u_n \sim \sqrt{\frac{\pi}{2n}} To prove this, first note that for any fixed \delta > 0, \int_\delta^{\pi 2} \cos^{n} (\sin x) \, dx = O(r^n), where r = \cos \sin \delta This is
How to evaluate $\\int_{0}^{\\frac{\\pi}{2}} \\frac{\\cos(x)}{(1 . . .
FWIW Mathematica can get a very messy antiderivative (I've checked up to n = 10, although the one it gives for n = 1 does not appear to agree with numeric integration, likely due to branch cuts) The integral is a rational number except n=1

$$ \int_0^{\frac{\pi}{2}} \frac{x}{\sin x} dx \\ \sum_0^{\infty} \frac{4^n}{\binom{2n}{n}(2n+1)^2}$$ You can rewrite it as the following using the definition of the central binomial coefficient:
