Just a place to try some of the new TeX stuff out.
<math>A_{b_c} A^{b^c}<math>
<math>R_s = \left\{ \frac{\sin (\theta_i - \theta_t)}{\sin (\theta_i + \theta_t)} \right\}^2<math>]
<math> A \mathbf{A} \theta \mathbf{\theta} \boldsymbol{\theta} <math>
<math>\mbox{Area}(0,\theta) =
\frac{AB}{2} \left\{
\theta - \operatorname{atan}
\left[
\frac{\sin(2 \theta)}
{ \cos(2 \theta) +
\left(
\frac{B+A}{B-A}
\right) }
\right]
\right\}
<math>
<math>\alpha \propto<math>
<math>I_{mn} (x,y) = I_0 \left[ \mbox{H}_m \left( \frac{ \sqrt{2} x}{w} \right) \exp \left( \frac{-x^2}{w^2} \right) \right]^2 \left[ \mbox{H}_n \left( \frac{ \sqrt{2} y}{w} \right) \exp \left( \frac{-y^2}{w^2} \right) \right]^2 <math>
