Math Test with KaTeX
This is a test post to verify that KaTeX is properly rendering mathematical formulas. Inline Math Here is an inline equation: \( E = mc^2 \) and another one using dollars: $ a^2 + b^2 = c^2 $. Block Math Here is a block equation using double dollars: $$ f(x) = \int_{-\infty}^\infty\hat f(\xi)\,e^{2 \pi i \xi x}\,d\xi $$And another one using brackets: \[ \mathbf{V}_1 \times \mathbf{V}_2 = \begin{vmatrix} \mathbf{i} & \mathbf{j} & \mathbf{k} \\ \frac{\partial X}{\partial u} & \frac{\partial Y}{\partial u} & 0 \\ \frac{\partial X}{\partial v} & \frac{\partial Y}{\partial v} & 0 \end{vmatrix} \]If these render beautifully, then KaTeX is fully integrated!
