sum notation
How do you type the parameters for $\sum$ and $\int$ and when i do $\lim$ how do I put a $n \rightarrow \infty$ under it

Just click the Latex images to see the code.

$\sum_{i=1}^{n}$

$\int_{a}^{b}f(x)dx$

$\lim_{x \rightarrow 0} f(x)$

or if you're writing a latex document, where the "displaystyle" is not activated, you can write :

\sum\limits_{n=1}^{\infty}
