MaximaPHP
Provides Maxima online, a system for the manipulation of symbolic and numerical expressions, including differentiation, integration, Taylor series, Laplace transforms, systems of linear equations, polynomials, and sets, list, vector, matrices and tensors.
Dedicated to the memory of William Schelter.
Graphics plotting is made possible by Gnuplot 4.2.0.
Thanks to Ian Hutchinson who provided TtM to convert TeX to MathML.
IE users may want to install MathPlayer plugin from Design Science or just convert to Firefox.

You can refer to the last output and input using variables %lo and %li respectively.
Additionally variable %lx is used internally by MaximaPHP.
This examples are obtained using example(...) command from Maxima.
