Math mode ($ vs. $$)

Putting text between dollar signs will activate "math mode" where you can format equations and code in TeX. A single pair of dollar signs (e.g. $y = mx + b$) produces in-line math mode (ie able to use symbol for $\lambda$)


A pair of dollar signs (e.g. $$y = mx + b$$) will bump it to the next line and center it on the assignment page in a more prominent display, centered on the &.


ex:


Displays as:

Notice that \cr is needed at the end of all except the last line (to close the line), and the equations as a whole are bookended with $$ { } $$


Use those curly brackets! { } are your friend!


subscript: _

superscript: ^


Bold

$\bf{XXX}$

where XXX is what you want bolded


horizontal spacing within (text formatting)

\;

\enspace



alignment: \eqaline


skips for vertical spacing:

\smallskip

\medskip

\bigskip


indentation:

\indent


for no indentions

\noindent


To display $ is a bit tricky, since it's used to indicate math type.

$\$ monetary unit


note that to call variables (@ans1) math type (ie hugging it in $    $ ) is not needed.


feel free to google what you're looking for with TeX as well

ex: square root TeX

\sqrt{expression}
