Here is an example of how to input math:

$\int_0^\pi\sin x\,dx = \left[ -\cos x\right]_0^\pi = -(-1)-(-1)=2$

How do you compute the derivative of

$\frac{x^2+1}{3x^4-7}?$

just for testing:

$\int_a^bf'(x)\,\mathrm{d}x=f(b)-f(a)$

$\Gamma(z)=\int_0^\infty t^{z-1}\mathrm{e}^{-t}\,\mathrm{d}t$

$f^{(n)}(z)=\dfrac{n!}{2\pi\mathrm{i}}\oint_\gamma\dfrac{f(t)}{(t-z)^{n+1}}\,\mathrm{d}t$
