Homework #3 – LaTeX Scratchpad – due Thursday, September 28

September 26, 2017 / Kate Poirier / 21 Comments

$\LaTeX$ (pronounced LAY-teck) is a commonly used language for typesetting math. There are many ways to use $\LaTeX$ to create professional looking documents (most involve installing an implementation on your computer) but you can also use $\LaTeX$ to type math right in your OpenLab posts.

Professor Reitz has some great instructions for using $\LaTeX$ on the OpenLab here (scroll to “Typing math on the OpenLab”).

It can take some getting used to, your homework is to practice by submitting a comment on this post. Don’t worry about typing something that makes any mathematical sense, just try typing anything. Play around and make a giant mess in these comments. If something doesn’t work at first, don’t worry; just try again. (Note that your first OpenLab comment will have to be approved before it appears.)

You can mouse-over something to see what LaTeX code was. For example, mouse-over this: $\frac{d}{dx} \left( \int_a^x f(t)dt \right) = F(x)$ to see what I entered.

If you submit something that LaTeX doesn’t understand, it will display “formula does not parse” but you can also mouse-over that to see what was submitted.

Hi,
I am sorry. I am just trying to apply Latex here

  Hi Hanan. Don’t forget to close up with another dollar sign at the end!

  Hi Violanda. Don’t forget to add a space after latex but before \frac.
