The formula $S$ for a sphere of radius $R$ in spherical coordinates is:
$S=\left\{0\le \varphi \le 2\pi ,0\le \theta \le \pi ,0\le \rho \le R\right\}$

## NOTES:

I hope this site can be used as a learning aid (tutorial by example) for mathematics in TeX/LaTeX and in coding MathML.
A small sample of many different types of mathematical expressions and equations is shown.
All the examples are complete with the source code available. (Just click on the equation/formula.)

### Lessons Learned Working on MathML with STIX Fonts on Firefox:

When using an `mtable`, the table cell (`mtd`) default vertical padding produces excessive spacing. Setting the top and bottom padding to zero "`0`" fixes this.

When using the `mfenced` tag, the "fences" have no spacing around them.
When using the vertical bar "|" (`&vert;`) as a fence, adding a little spacing around it improves the readability of the result.

Firebug is an add-on to the Firefox browser. It is a great development tool that works well with MathML.
