My first time with LaTeX

Each mathematical formula I have used in my blog till now was an image: I wrote them in a Word document using the equation editor by Microsoft (that I like very much), then I captured the screen and saved it as an image and then I uploaded them in my blog.

In the past, I tried to find a way to write them as text, without succeeding. But in fact, it is possible, using the LaTeX syntax and a few HTML commands.

These are the first “true” mathematical formulae present in this blog. I will use this page to test the LaTeX syntax for mathematical expressions (a handbook is available here).

\int_{A_1}\int_{A_2}\frac{\partial \Psi(x,y)}{\partial x}dxdy

i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>

A symbol within the paragraph: \pi. A inequality within the paragraph: x_i>0. This is an example of an expression with a pedix that has a pedix: f_{X_1}.
