MathML Samples

This page contains sample equations represented by MathML markup. The page has been configured to always use HTML-CSS mode with web fonts to display the equations, which produces uniform layout and typesetting across browsers.

$$x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$$ $$f\left(a\right)=\frac{1}{2\mathrm{\pi <!--\; \pi \; -->}i}{\oint }_{\gamma }\frac{f\left(z\right)}{z-a}dz$$ $$\cos (\theta +\phi )=\cos \left(\theta \right)\cos \left(\phi \right)-\sin \left(\theta \right)\sin \left(\phi \right)$$ $${\int }_D(\nabla \cdot F)dV={\int }_{\partial D}F\cdot ndS$$ $$\overrightarrow{\nabla }\times \overrightarrow{F}=(\frac{\partial F_z}{\partial y}-\frac{\partial F_y}{\partial z})i+(\frac{\partial F_x}{\partial z}-\frac{\partial F_z}{\partial x})j+(\frac{\partial F_y}{\partial x}-\frac{\partial F_x}{\partial y})k$$ $$\sigma =\sqrt{\frac{1}{N}{\displaystyle \sum _{i=1}^N{(x_i-\mu )}^2}}.$$ $${\left({\nabla }_{X}Y\right)}^k=X^i{({\nabla }_{i}Y)}^k=X^i(\frac{\partial Y^k}{\partial x^i}+{\Gamma }_{im}^k{Y}^m)$$
