is generated by $\sum_{i=3}^{11}x^2$

is generated by $\prod_{x\in(x)}\cos x^2$ -- note \cos rather than cos so LaTeX knows it's a function, and doesn't italicize it.

is generated by

$\lim_{x\to\infty} \int_0^{4{\pi}} \binom{n+m}{n-m} \sqrt[3]{\frac{2 + \cos x}{2 - \sin x}} dx$
note the optional [3] to make the cube root
note: \limsup, \liminf, \sup, \inf work the same as \lim, changing only the word(s) displayed.

is generated by $\mathbb{R\quad Q\quad Z}$ blackboard bold font for reals, rationals, integers

is generated by

$\left|\sum_{i=1}^n a_ib_i\right| \le \left(\sum_{i=1}^n a_i^2\right)^\frac{1}{2} \left(\sum_{i=1}^n b_i^2\right)^\frac{1}{2}$

is generated by $H(x)=\left\{\begin{array}{cl} 0, & x<0 \\ 1, & x\geq 0 \end{array}\right.$

is generated by $I_n = \left[ x^{n-2}\frac{2}{3} \sqrt{1+x^3} - (n-2)\int x^{n-3}\cdot\frac{2}{3} \sqrt{1+x^3}\textrm{d}x \right]_0^1$

 is generated by $\underbrace{\overline{A}=\left(\begin{array}{ccc|c} \ast & \ast & & \\ \ast & \ast & \ast & \\ & \ast & \ast & \\ \hline & & & \ast \\ \end{array}\right)}$ Note: array argument c=center, l=left, r=right, |=vertical line

 is generated by $0 < |x-c| < \delta \Rightarrow |f(x) - L| < \varepsilon$
