Key Equations

$$V(x) = \begin{cases} -V_0 & |x| < a \\ 0 & |x| > a \end{cases}$$
$$k\cot(ka) = -\kappa$$
$$E_0 \approx -V_0 + \frac{\pi^2\hbar^2}{8ma^2} = -10\,\text{eV} + \frac{\pi^2(1.055 \times 10^{-34})^2}{8(9.11 \times 10^{-31})(10^{-9})^2}$$
$$k_{\text{in}} = \frac{\sqrt{2m(E+V_0)}}{\hbar}, \quad k_{\text{out}} = \frac{\sqrt{2mE}}{\hbar}$$

Equations are rendered with MathJax in the PDF with professional LaTeX typesetting.
