## LaTeX

Did you know you can write mathematics in WordPress blog posts?  It’s easy.  To add an equation to a post, you surround your math with $latex’ at the beginning and $’ at the end. So, you write

$latex YOUR MATH HERE$

You can use symbols like + x – and for exponents you can write ^.  For subscripts you can use _.  So for example,

$latex x^2y_3+6=z_2^7$

produces

$x^2y_3+6=z_2^7$

You can also write fractions this way:

$latex \frac{a}{b}$

producing

$\frac{a}{b}$

You can make a permutation by writing

$latex (12)(345)$

which gives

$(12)(345)$

And you can make a matrix this way:

$latex \begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix}$

and you’ll get

$\begin{pmatrix} 1 & 2 & 3 \\ 4 & 5 & 6 \\ 7 & 8 & 9 \end{pmatrix}$

1. Oh, and for proofs you can make the little square $\square$ with the command \square.

2. Also, LaTeX can do polynomial long division for you automatically:

this might be useful on the next pset 🙂

3. Wow. See, that’s why LaTeX rocks. It will do your homework for you.

4. Let me try whether it works!

Solve the Diophantine equation: $x^3=y^63=z^3$

5. You mean
$x^3+y^3=z^3$ ?

Does wordpress support Latex support in posts also?

6. Please I still don’t understand how to type maths in a wordpress dashboard using latex.

7. \$latex I’m writing latex

8. $I’m writing latex$

9. test

$x^3+y^3 = z^3$

10. test

$x^3 + y^3 \mapsto z^3$
