# [Tex/LaTex] Laplace’s Equation Symbol

greeksymbols

I used \nabla to present the laplace equation but it doesn't work, is there any method to write the del operator (Gradient) symbol?

here an example:

\documentclass[border=10mm]{standalone}
\begin{document}
$$\nabla (fg)= f\nabla g + g \nabla f$$

\end{document}


it yields:

if this does not work there must e something wrong with your TeX installation.
