[/color]\bigg[ (3x)^2 + 7 \bigg] produces:[color=beige] .[/color] I found that \big[ and \big] will produce:[color=beige] .[/color] Hence, f\big(g(x)\big) will produce:[color=beige] .[/color] [color=beige]. . [/color]And I like the subtler difference in sizes.

I usually use \left and \right and have (the fake) LaTeX work out the sizes for me.

In addition to the command you listed for rightarrow, you can also use the command \Rightarrow (with the first letter capitalized) for the doubleshafted arrow used for "implies." So if you want to write that , your command is P \Rightarrow Q.

I love ! It's definitely a skill worth picking up. It's so much nicer and more professional than Microsoft Word. I've only taught lower division and developmental math, but I use for all of my handouts, syllabi, and tests/quizzes! I even use it for alot of my word processing!

Does anyone know how to format polynomial long division in LaTeX?

I tried a number of techniques and could not get the expressions to line up, [color=beige]. . [/color]nor could I control the underlining. So I developed this very clunky format . . . using \begin{array} I chart it out on a grid. Every term and sign gets its own space, except the divisor. Then I count the blank spaces that are needed. The code looks like this. [Maybe some of you have the stamina to read through it?] [latex ]\begin{array}{ccccccccc} &&&& x^2 &  & 5x &  & 6 \\ &&  &  &  &  &  &  &  \\ x2 &  & x^3 &  & 7x^2 & + & 4x & + & 12 \\ && x^3 &  & 2x^2 \\ &&  &  &  \\ &&&& 5x^2 & + & 4x \\ &&&& 5x^2 & + & 10x \\ &&&&  &  &  \\ &&&&&& 6x & + & 12 \\ &&&&&& 6x & + & 12 \\ &&&&&&  &  &  \end{array}[/latex]
