The effect of such markup as \tiny and \small doesn't persist if you wrap it in braces. For example, x^{\small2} is fine.

Thanks for that very useful tip!

Re: Some Latex Commands



Discovered this by accident . . .


I often use \bigg[ and \bigg] for oversized brackets.

[color=beige]. . [/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.

Re: Some Latex Commands

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

Re: Some Latex Commands

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

Re: Some Latex Commands

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!

Re: Some Latex Commands


I am very anal about spacing . . .


[color=beige]. . [/color]4\sin^2(3theta)[color=beige] . . . . . [/color]

[color=beige]. . [/color]4[color=red]\,\![/color]\sin^2(3\theta)[color=beige] . . [/color]


[color=beige]. . [/color]\ln(x^3)[color=beige] . . . . [/color]

[color=beige]. . [/color]3\ln(x) [color=beige] . . . . .[/color]

[color=beige]. . [/color]3[color=red]\,\![/color]\ln(x) [color=beige] . . [/color]


[color=beige]. . [/color]x\sqrt{x^2-2x-3} [color=beige]. . . . . . . . [/color]

[color=beige]. . [/color]x[color=red]\,[/color]\sqrt{x^2[color=red]\,[/color]-[color=red]\,[/color]2x[color=red]\,[/color]-[color=red]\,[/color]3} [color=beige]. . [/color]

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

Hello, greg1313!

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 \\
&& -- & -- & --- & -- & --- & -- & -- \\
x-2 & | & x^3 & - & 7x^2 & + & 4x & + & 12 \\
&& x^3 & - & 2x^2 \\
&& -- & -- & --- \\
&&&& -5x^2 & + & 4x \\
&&&& -5x^2 & + & 10x \\
&&&& --- & -- & -- \\
&&&&&& -6x & + & 12 \\
&&&&&& -6x & + & 12 \\
&&&&&& --- & -- & --
\end{array}[/latex]
