LaTeX equations do not render in google Colaboratory when using IPython.display.Latex

Question

In a regular jupyter notebook, running, for example, the following:

from IPython.display import display, Math, Latex
display(Math(r'F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx'))

produces an equation rendered in LaTeX (via Mathjax).

Even though LaTeX works fine in markdown cells, LaTeX equations produced as above do not seem to render in Google Colaboratory. The same happens to the output of functions for example from qutip, which would normally render in latex (for example, qutip.basis(2, 0) would normally render in latex, but doesn't in Colaboratory).

Why does this happen? Is there a way to have this work?

Answer 1

Update (April / 2021):

It's possible to write formulas in Colab just putting them between $ symbols, with no need to import libraries:

$F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx$

Old answer

As an alternative, the following description should work on text cell on Colab.

\begin{equation}

F(k) = \int_{-\infty}^{\infty} f(x) e^{2\pi i k} dx

\end{equation}

Answer 2

An alternative is to use it as markdown with githubusercontent (source) instead a codeline on Colab, add a text (markdown text) and then to use the next line. e.g.

<img src="https://render.githubusercontent.com/render/math?math=e^{i \pi} = -1">
