Page: http://people.revoledu.com/kardi/tutorial/LinearAlgebra/VectorTripleCrossProduct.html Properties: \"Similarly, ...\" (and the preceding property) -- use either (a^T c) or (a . c), but not (a^T . c). Also, have you considered converting this website to use Sphinx? It makes fantastic websites, and allows you to write your math inline in the rst source files as LaTeX formulas. -- http://sphinx.pocoo.org/

On http://people.revoledu.com/kardi/tutorial/LinearAlgebra/VectorCrossProduct.html, the equation in the property starting \"The magnitude of vector cross...\" is missing norm-bars. In other words, a x b => ||a x b||. There is also a mysterious \'m\' or \'n\' in the RHS of the equation.

Thanks Mark for the report. The vector n is the cross product result explained in the figure right below the properties. To make it clearer, I fixed the equations that you have pointed out. Thanks also for the tips on Sphinx.
