Help me in my problem, please: I need to produce some symbolic calculations (algebraic transformations, integration, differentiation, etc.) in the program on Pascal. Therefore, I am looking for a symbolic processor which can be directly included into the program as a unit or library (from this point of view, Maple, MathLab etc. are useless). Too well if it would be free software.
