### Testing Math ML

This formula by Ramanujan is being rendered by MathJax. The equation was derived from the handwriting-to-MathML utility, Web Equation, and then hand edited a bit.  This formula served as a basis for our Python Pi Day contest last year, at OST.

Right click on the equation and choose Show Source to look at the MathML.

In LaTex (I didn't need to edit this one): $$\dfrac {1} {\pi }=\dfrac {\sqrt {8}} {9801}\sum _{n=0}^{\infty }\dfrac {\left( 4n\right) !} {\left( n!\right) ^{4}}\left[ \dfrac {26390n+1103} {396^{4n}}\right]$$
Ramanujan's crazy-making identities get mentioned by me a few times in this debate thread on math-teach.
