### LaTeX

(It’s Infomercial Time!)

Hello viewers! Today we have a product that could CHANGE YOUR (mathematical) LIFE! It’s called LaTeX, and this amazing product allows you to write mathematical expressions in WordPress in a nice, professional form! And it could be yours free if you blog with WordPress! Let’s go to the demonstration, shall we?

So if you’re writing a post about math, and you want to write some complicated expression that you can’t figure out how to… express, then use LaTeX! Let’s transform this ugly expression, A = π(r^2), which is the formula for the area of a circle. You can’t write exponents with normal text, so we’re gonna use LaTeX. Ready? 3, 2, 1!

$A = \pi r^2$

WOW! What a makeover! LaTeX has done it again! You have all the symbols there! Let’s try with something else, like a square root. It’s possible to express square roots with the special character √, but that has some ambiguity on where the square root ends. LaTeX makes it unambiguous.

√(a+b) ≠ √a + √b

$\sqrt{a+b} \neq \sqrt{a} + \sqrt{b}$

You can change colors, too.

So yeah, LaTeX is great. But how do you use it? Simply put “$latex” without the quotes when you want to start a LaTeX expression, then to end it, just put “$”. There’s a whole lot of things you have to do to produce your equation, AKA special notation, but to bypass that, use this link: http://www.codecogs.com/latex/eqneditor.php It automatically generates the code for you, so all you have to do is copy that and paste it between “$latex” and “$”.
