$\int x^{2}\sqrt{a^{2}+x^{2}}\,dx$. Is there another way to solve it faster?

I can't find the pattern while evaluating $\int_0^{\pi/2}\sin^n(x)\,dx$

Express an integral in terms of another integral.

Does $\int1+\sin^2x+\sin^4x+\sin^6x+...\text{dx}=\tan{x}$?

Integrate $\frac{\theta \sin \theta}{1+\cos^2 \theta}$ with respect to $\theta$

Evaluating $\int_{0}^{2\pi}\frac{1}{\cos^2(\theta)+1}\, d\theta$

How do you find appropriate trig substitution for $\int \frac{\sqrt{16x^2 - 9}}{x} \, dx$?

Integral $I(\tau_1,a,b) = \int_{\tau_1}^\infty d\tau_2\ \frac{1}{b^2 + \tau_2^2} \left(\pi - 2 \tan^{-1} \frac{\tau_2}{a} \right)^2$
