Hi, I am wondering if anyone knows of a good program that will solve algebraic formulas symbolically. I was using Mathematica under Windows to do this. I need something to solve the equations for bilinear transform of filters to the digital domain. I can't (don't) have the patience to work the algebra out by hand (it is not usually trivial, with large powers of complicated polynomials). I looked at Octal but it is just a mathematical programming language, not a symbol solver. Is there any free software which can be programmed to solve algebraic formulas (like Mathematica) available?
