PyCalc Help
Symbolic Math
PyCalc includes the Sympy Python package — a very large package that has a huge number of capabilities. See this link for more information.
Symbolic math is one of the things that Sympy can do.
You can import the Sympy package into your Python environment by adding: import sympy
into your startup.py.
If there is sufficient interest a symbolic mode could be added to PyCalc to make sympy easier to use, similar to Matrix Mode.
