Hi,   
      
   I just released Algebrite, a Javascript library for symbolic mathematics,   
   keeping the code as simple as possible in order to be comprehensible and   
   easily extensible.   
      
   Supports:   
     Arbitrary-precision arithmetic   
     Complex quantities   
     Simplification   
     Expansion   
     Substitution   
     Symbolic and numeric roots   
     Units of measurement   
     Derivatives and gradients   
     Tensors   
     Symbolic and numeric integrals, multi-integrals   
      
   http://algebrite.org/   
      
   (where also a sandbox is provided to try it from the browser).   
      
   Based on the EigenMath project by George Weigt.   
      
   Cheers,
