How to Enter Math in Rhea
This page shows many of the functions and symbols that you are likely to need while working on the practice problems. *hint hint
Basics of Rhea/Wiki Math
Math in Rhea is written using the Latex commands. To begin, you need use the math tags like: <math> formulas </math>.
Resources
You should know that there is a host of resources already to help you along. One great page on Rhea is How to type Math Equations. Another resource is Wikipedia's page on Functions, Symbols, and Special Characters.
| Description | What it looks like | What you type |
|---|---|---|
| Summations | $ \sum_{n=-\infty}^\infty x[n]e^{-j2\pi f} $ | \sum_{n=-\infty}^\infty x[n]e^{-j2\pi f} |
| Summations with Delta | $ \sum_{k=0}^\infty x[n]\delta [n-k] $ | \sum_{k=0}^\infty x[n]\delta [n-k] |
| Fractions | $ y=x^2/2 +\frac{x}{\phi} $ | y=x^2/2 +\frac{x}{\phi} |
| Integrals | $ \int\limits_{\alpha}^{\beta}e^\tau\ d\tau $ | \int\limits_{\alpha}^{\beta}e^\tau\ d\tau |
| Braces and Script Characters | $ \mathcal{F }\left \{ rect(t) \right \}, \mathcal{X}(\omega) $ | \mathcal{F }\left \{ rect(t) \right \}, \mathcal{X}(\omega) |
| What it looks like | What you type |
