English: $- \hslash^{2}(\frac{1}{sin\theta}\frac{\partial}{\partial\theta}\left( sin\theta\frac{\partial}{\partial\theta} \right) + \frac{1}{\theta\ }\frac{\partial^{2}}{\partial\phi^{2}})$ So, I know that the Laplacian is $\frac{1}{r^{2}}\frac{\partial}{\partial r}\left( r^{2}\frac{\partial}{\partial r} \right) + \frac{1}{r^{2}sin\theta}\frac{\partial}{\partial\theta}(sin\theta\frac{\partial}{\partial\theta}) + \frac{1}{\theta\ }\frac{\partial^{2}}{\partial\phi^{2}}\ $.
