Typesetting equations

In the following cell, use Markdown and LaTeX to typeset the equation for the probability density of the normal distribution $f(x, \mu, \sigma)$, which can be found here. Following the main equation, write a sentence that defines all of the variable in the equation.

YOUR ANSWER HERE: \begin{equation*} \Large{ f(x, \mu, \sigma) = \frac{1}{\sigma \sqrt{2 \pi}}e^{-\frac{(x-\mu)^2}{2\sigma^2}} } \end{equation*};
$\mu$ = the mean or expectaion of distribution.;
x = position;
$\sigma$ = standard deviation.

In the following cell, use Markdown and LaTeX to typeset the equation for the time-dependent Schrodinger equation for non-relativistic particles shown here (use the version that includes the Laplacian and potential energy). Following the main equation, write a sentence that defines all of the variable in the equation.

YOUR ANSWER HERE: $ \large{i\hbar \frac{\partial}{\partial t}\Psi(r,t) = \left[\frac{-\hbar^2}{2\mu}\nabla^2 + V(r,t) \right]\Psi(r,t) }$;
$\mu$ = particles reduced mass;
$V$ = potential energy;
$\nabla^2$ = laplacian;
$\Psi$ = position-space wave function.

In the following cell, use Markdown and LaTeX to typeset the equation for the Laplacian squared ($\Delta=\nabla^2$) acting on a scalar field $f(r,\theta,\phi)$ in spherical polar coordinates found here. Following the main equation, write a sentence that defines all of the variable in the equation.

YOUR ANSWER HERE: $\large{ \Delta f = \frac{1}{r^2}\frac{\partial}{\partial r} \left(r^2 \frac{\partial f}{\partial r} \right) + \frac{1}{r^2 \text{sin} \theta}\frac{\partial}{\partial \theta} \left(\text{sin} \theta \frac{\partial f}{\partial \theta} \right) + \frac{1}{r^2 \text{sin}^2 \theta}\frac{\partial ^2 f}{\partial \psi ^2} }$;
$r$ = distance from origin;
$\theta$ = zenith angle (angle from z-axis);
$\psi$ = should be $\phi$, azimuthal angle (angle around xy-plane).
