If have the code :

# ```{python}

from sympy import *

from IPython.display import display

init_printing(use_latex='mathjax')

x=symbols('x')

d=diff(sin(x)/cos(x), x)

print(latex(d))

#```

This prints correctly:

## \frac{\sin^{2}{\left(x \right)}}{\cos^{2}{\left(x \right)}} + 1

But offcourse I need this latex rendered , not the text, in my document.

I tried init_printing(use_latex='mathjax') , but no ...
