This week’s question comes from Brian, who is a part-time math teacher:

*How do you plot trigonometric functions in degrees instead of radians?*

Trigonometric functions in *Mathematica* such as `Sin[x]` and `Cos[x]` take *x* to be given in radians:

Got questions about *Mathematica*? The Wolfram Blog has answers! Each week, we’ll answer a selected question from users around the web. You can submit your question directly to the Q&A Team.

For our first post in this new series of *Mathematica* Q&A articles, we’re going to address a very frequently asked question about plotting in *Mathematica*.

**How can I control the appearance of discontinuities in a plot?**

The short answer is, use the options `Exclusions` and `ExclusionsStyle`! Let’s see how they work.

By default, `Plot` shows the function 1 ⁄ sin(*x*) with lines joining its discontinuities:
