To embed equations using precede your code with “latex” and sandwich this with $ as follows [1][2]:

**$****latex your-latex-code$**

To change the size precede the last $ sign with **&s=2** like this:

**$****latex your-latex-code &s=2$**

where 2 is the size which could be any number (as far as I know). For example, the Schrödinger equation above is of size 2. It was generated using:

**$ latex i\hbar\frac{\partial}{\partial t}\left|\Psi(t)\right>=H\left|\Psi(t)\right>&s=2**

**$**
