These are matters of taste, I use both & find Mathematica's notebooks much better than Jupyter. Editing text in a web browser is just painfully clumsy, and plain text is not great for reading mathematical expressions of any length. But obviously it depends what you're doing with it.

You complain about Sin[] but not about ugly things like np.sin()? Also I think you're looking for

    Sin[θ] //TraditionalForm //TeXForm

[pletnes]

Using \text{} instead of \sin is, arguably, plain incorrect. Or at least at odds with the tex philosophy of separation between content and formatting.

Yeah, I guess that is fair. It might just be that it is more or less the furthest way from how I like to work as I can imagine.

> Sin[θ] //TraditionalForm //TeXForm

Did not know of this. Thanks!

[henrikeh]

TeXForm automatically applies TradionalForm unless another *Form is applied.

So TeXForm[Sin[x]] gives "\sin (x)"

[improbable22]

Indeed, sorry! It even says so in the help.

And while I swear I've had rotorblade's problem before, right now "Copy as LaTeX" seems to do this too.
