Functions I Frequently Use

Fraction

Multiplication
 not write a multiplicationsign at all, as in $y=mx+c$
 or you should write it using a vertically centered dot, as in $3\cdot5=15$. Do not use symbols like “
*
”! In LaTeX you use the command \cdot
to make a multiplicationdot.
 Sometimes you can use the symbol $\times$. Code
\times
is used in LaTeX to make the symbol

Dynamic Bracket Size
 The size of brackets and parentheses can be manually set, or they can be resized dynamically in your document, as shown in the next example:
$F = G \left( \frac{m_1 m_2}{r^2} \right)$
will produce the following output: $F = G \left( \frac{m_1 m_2}{r^2} \right)$
 Notice that to insert the parentheses or brackets, the
\left
and \right
commands are used. Even if you are using only one bracket, both commands are mandatory. \left
and \right
can dynamically adjust the size, as shown by the next example:

 use this template to get the step calculation similar to example below
$$
\begin{align*}
Ent\\
&= CR + PO \\ &= CR + (RC_{roy}CR)\cdot70\% \\
\text{if C below cost ceiling} \\
&= C + (RC_{roy}C)\cdot70\% \\
&= 0.7R  0.7C_{roy} + 0.3C
\end{align*}
