I heard a lot of you talking in the hall about how you were having trouble with writing a limit on your blog. I decided to give y’all a tutorial!

**Enter all of these codes in order on one line. starting with the number 1.**

Here is how you do it. There are 5 codes you will need.

- $latex
- \overset
- {lim}
- {x \rightarrowk}
- $
- f(x)
- =
- Then write whatever the limit is. For example “= DNE”
- It should look this without numbers 1: \overset{lim}{x \rightarrow k}$ f(x)= DNE
- If you entered it right, it should look like this: f(x)= DNE

Here is help with writing the lim of the difference quotient. There are 8 codes you will need:

- $latex
- \overset
- {lim}
- {h \rightarrow 0}
- $
- $latex
- \frac {f(x+h)-f(x)}{h}
- $
- Then write whatever the limit is equal to. For example “= DNE”
- It should look like this without number 1: \overset {lim}{ h \rightarrow 0}$
- If you entered it right, it should look like this:

Here are some FUN latex codes you can do:

Smiley Face:

- $latex
- \overset
- {\bullet \bullet}
- {\smile}
- $
- It should look like this without number 1: \overset {\bullet \bullet}{\smile} $

Bow Tie Smiley Face

- $latex
- \overset
- {\overset {\bullet \bullet}
- {\smile}}
- {\bowtie}
- $
- It should look like this without number 1: \overset {\overset {\bullet \bullet}{\smile}}{\bowtie} $

Scared Face

- $latex
- \overset
- {\odot \odot}
- {\circ}
- $
- It should look like this without number 1: \overset {\odot \odot}{\circ} $

Mustache Face

- $latex
- \overset
- {\overset {\bullet \bullet}
- {\overbrace{}}}
- {\smile}
- $
- It should look like this without number one: \overset {\overset {\bullet \bullet}{\overbrace{}}}{\smile} $

Heart

- $latex
- \heartsuit
- $
- It should look like this without number 1: \heartsuit $

**HOPE THIS TUTORIAL WAS HELPFUL!**

cute! $latex\overset {\overset {\bullet \bullet}{\smile}}{\bowtie} $

aw boo! let me try again… $latex\overset{\overset {\bullet \bullet}{\smile}}{\bowtie}$

Those are adorable faces!
