How can I post an equation in textbook form?

Question

I am trying to describe a differential equation I am putting into NDSolveValue. However, it is complicated and I would like to express it in textbook form before I show how I have put it into Mathematica form. I have tried copying from traditional form but this does not work. Any suggestions?

Trying the suggestion I wish to copy the Laplacian so the Mathematica form is

Laplacian[\[Phi][x, y, t], {x, y}]

then using TexForm

TeXForm[Laplacian[\[Phi][x, y, t], {x, y}]]

which gives

\phi ^{(0,2,0)}(x,y,t)+\phi ^{(2,0,0)}(x,y,t)

You then have to put a $ before and after as a delimiter.

$\phi ^{(0,2,0)}(x,y,t)+\phi ^{(2,0,0)}(x,y,t)$

This is not converting to textbook form here but it works fine on the main site. Thanks for the suggestions.

Answer 1

You may also highlight the output formula and select to Copy As | LaTeX.

This will paste as LaTeX.

\phi ^{(0,2,0)}(x,y,t)+\phi ^{(2,0,0)}(x,y,t)

This has the benefit of not needing to type in TeXForm. It also works on other formatted output like Grid.

Grid@Table[i - x^j, {i, 2}, {j, 2}]

\begin{array}{cc} 1-x & 1-x^2 \ 2-x & 2-x^2 \ \end{array}

Hope this helps.
