Markdown and Math Equations

Using Streamlit
#1

Hey everyone,

I am having trouble with Markdown and Latex support. In the API Reference, it says St-supported functions are on Katex webpage. However, I can’t get a simple frac to work. Actually, I am looking for a tool that will show exactly what will be shown in Streamlit. I have used StackEdit – In-browser Markdown editor, however, the behavior is different in Stackedit and Streamlit. Do you have any tool or extension for Vscode? And what I am doing wrong below?
st.markdown(
“”"
$$\frac{a}{b}$$
“”"

Result:

I think we should put r before “”". However, there are some cases where it works without r. Can anyone explain the smart way of working on these equations? I will write long engineering documentations for my Streamlit apps.

For me it works well if I use it the follwing way with the $$ on a separate line:

latext = r'''
## Latex example
### full equation 
$$ 
\Delta G = \Delta\sigma \frac{a}{b} 
$$ 
### inline
Assume $\frac{a}{b}=1$ and $\sigma=0$...  
'''
st.write(latext)

As you did, there should be a r before the “”" “”". Thank you.
