1. ## Sigma question

I can make the sigma/Sigma notation. How do I make the superscripts/subscripts to go along with it?

$$\sum\limits_{k = 1}^N {\sin (k)}$$ gives $\sum\limits_{k = 1}^N {\sin (k)}.$

3. You can also use \displaystyle \sum, i.e. $\displaystyle \sum_{n=n}^{n>n}$ (click to see the code).

You can use [ noparse] [/noparse] to desplay the code. (remove the extra space)
$$\displaystyle \sum_{n=n}^{n>n}$$
