Do you want to work collaboratively on scientific formulas?
Use the Helmholtz Cloud service HedgeDoc notes.
You can render LaTeX mathematical expressions using the $ delimiter.
Here an example with the Fourier Transform that you can directly try in a Hedgedoc note if you have one open:
1
2
3
$$
\mathcal F(f):\xi \mapsto \hat{f}(\xi) = \int_{-\infty}^{\infty} f(x) e^{-{\rm i}\xi x}\, dx
$$
It will render like this*:
\[\mathcal F(f):\xi \mapsto \hat{f}(\xi) = \int_{-\infty}^{\infty} f(x) e^{-{\rm i}\xi x}\, dx\]It also works inline if you are writing simpler and not less magnificent formulas like $E = mc^2$: \(E=mc^2\).
The Helmholtz Cloud also offers more comprehensive tools with dedicated text editors for academia like Collabtex and SciFlow, both supporting LaTeX.
*That is because Codebase also uses MathJax, which is behind this feature in HedgeDoc. If you want to check what else HedgeDoc can do, have a look here.
