$$E=mc^2$$

$f(x) = \sqrt[3]{x^3} = \sqrt{x^2} = x = x^{\frac{2}{2}}$

$\theta = {5\pi \over 4}$

$\sin(\theta) = -{\sqrt{3} \over 2}$

$\lim_{n \to \infty}x_n$

$\int\limits_{1}^{3}\frac{e^3/x}{x^2}\, dx$

$$\begin{array}{lll} \int e^{x} \, dx &= e^{x} + C, \\ \int \sin x \, dx &= -\cos x + C, \\ \int \cos x \, dx &= \sin x + C, \\ \int x^{s} \, dx &= \frac{x^{s+1}}{s+1} + C, \, \text{ provided } s \neq 1,\\ \int \frac{1}{x} \, dx &= \ln |x| + C; \quad\text{ on intervals} . \end{array}$$
