Look at the file sample.pdf to see what the output looks like. Here's an example of inline math output: $y=\sin(x).$ Here's an example of output on a separate numbered line: \begin{equation} y=\sin(x) \end{equation} Greek letters: $\alpha \beta \gamma \Gamma \delta \Delta$ Subscripts and superscripts: $x_1$ $A_{i,j}$ $x^2$ $x^{2+\epsilon}$ $A_{i,j}^2$ Large parentheses and brackets on a separate line with no equation number: \[ \left[\left(x^2\right)^3\right]^4 = x^{24} \] Primes and integral signs: \[ \int_a^b f^\prime(x)\ dx = f(b)-f(a) \] Fractions and square roots: \[ \sqrt{\frac{1}{a+b}} \neq \frac{1}{\sqrt{a}}+\frac{1}{\sqrt{b}} \] \end{document}
