$$[ i\hbar\frac{\partial \psi}{\partial t} = \frac{-\hbar^2}{2m} \left( \frac{\partial^2}{\partial x^2} + \frac{\partial^2}{\partial y^2} + \frac{\partial^2}{\partial z^2} \right) \psi + V \psi ]$$
Here is $\rm \LaTeX$ inline, math representation of a circle ( \begin{align} x^2 + y^2 = 1 \end{align}) and here is Euler’s constant. $$e = \mathop {\lim }\limits_{n \to \infty } \left( {1 + \frac{1}{n}} \right)^n$$
