MathML Rendering Test

Joyee Cheung

Testing block and inline MathML rendering. Geometric series, finite and infinite:

\begin{array}{l} S_{n} = \sum_{k = 0}^{n - 1} r^{k} = \frac{1 - r^{n}}{1 - r}, r \neq 1 \\ S_{\infty} = \sum_{k = 0} r^{k} = \frac{1}{1 - r}, | r | < 1 \end{array}

RMSE, where $e_{i}^{2} = {(y_{i} - {\hat{y}}_{i})}^{2}$ and capacity grows as $2^{N - 1}$ :

\begin{array}{l} RMSE = \sqrt{\frac{1}{N} \sum_{i = 1} {(y_{i} - {\hat{y}}_{i})}^{2}} \\ NRMSE = 100 \cdot \sqrt{\frac{1}{N^{2}} \sum_{i, j} {(\frac{c_{i, j} - expected}{expected})}^{2}} \end{array}

Some inline bitwise stuff:
