 Description Calculate the Laplacian of a function.

Enter the function as an expression.

 >
 $\frac{{1}}{{2}}{}{{\theta }}^{{2}}{-}{3}{}{{ⅇ}}^{{\theta }}$ (1)

Specify the coordinate system, and then calculate the Laplacian of the function.

 > $\mathrm{VectorCalculus}\left[\mathrm{Laplacian}\right]\left(,{\mathrm{polar}}\left[{r}{,}{\mathrm{θ}}\right]\right)$
 $\frac{{1}{-}{3}{}{{ⅇ}}^{{\theta }}}{{{r}}^{{2}}}$ (2)
