### Mathematical formulae in blogs

I just discovered how to put latex into my blog:

\[\int_{-\infty}^{\infty} e^{-x^2}dx.\]

To see how go here.

Update: I see from the comment below that I can use XY-pic.

\[\usepackage[all]{xy}\color{Red}\xymatrix@C+2em@R+2em{

Q \ar@/_10pt/[ddr]_{q_1} \ar@/^10pt/[drr]^{q_2} \ar@{-->}[dr]|*+<3pt,3pt>{\scriptstyle u} & & \\

& P \ar[d]_(0.4){p_1} \ar[r]^(0.4){p_2} & Y \ar[d]^{g}\\

& X \ar[r]_{f} & Z

}

\]

Hi, thank you for using the script. I just want to let you know that you can use xypic package with this script. Here is an example:

\[\usepackage[all]{xy}\color{Red}\xymatrix@C+2em@R+2em{

Q \ar@/_10pt/[ddr]_{q_1} \ar@/^10pt/[drr]^{q_2} \ar@{-->}[dr]|*+<3pt,3pt>{\scriptstyle u} & & \\

& P \ar[d]_(0.4){p_1} \ar[r]^(0.4){p_2} & Y \ar[d]^{g}\\

& X \ar[r]_{f} & Z

}
