Simplifying expressions in SymPy

This article demonstrates how to simplify hyperbolic trigonometric expressions using Python's SymPy library, comparing results to Mathematica. It explains why certain simplifications like √(x−1)√(x+1) to √(x²−1) are not universally valid and shows how specifying variable domains (e.g., x ≥ 0) yields expected results.
