YouTube Video of the Week: Star Wars: The Last Jedi Trailer (Official)

This weeks video choice was easy... Very easy... From a galaxy far far away...

MathJax on Blogger Cheatsheet

1. Placement
$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$ will generate the formula inline \(\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}\) of a paragraph, where $$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$ will render the formula as a seperate image $$\sum_{i=0}^n i^2 = \frac{(n^2+n)(2n+1)}{6}$$ and not inline to the paragraph.

2. Greek letters
For Greek letters, use
$\alpha$ \(\alpha\)$\beta$ \(\beta\)$\delta$ \(\delta\) or $\Delta$ \(\Delta\)$\gamma$ \(\gamma\) or $\Gamma$ \(\Gamma\)$\ldots$ \(\ldots\)$\omega$ \(\omega\) or $\Omega$ \(\Omega\)
3. Superscripts and subscripts

For superscripts and subscripts, use ^ and _.
$x_i^2$ \(x_i^2\)$\log_2x$ \(\log_2x\)
4. Grouping

Superscripts, subscripts, and other operations apply only to the next “group”. A “group” is either a single symbol, or any formula surrounded by curly braces {…}.

If you do $10^10$, you will get a surprise: \(10^10\). But 10^{10} gives what you probably wanted: \(10^{1-}\).

Use curly braces to delimit a formula to whi…
