LanguageProject Introduction
Summary
SymPy provides a free, open-source library for symbolic computation in Python. It supports a wide range of mathematical operations from basic arithmetic to calculus, algebra, discrete mathematics, and quantum physics.
Problem Solved
Solving mathematical problems often involves symbolic manipulation (like simplifying expressions, solving equations analytically) rather than just numerical computation. SymPy addresses this need by providing powerful symbolic capabilities directly within the Python ecosystem, removing the need for proprietary or external CAS software.
Core Features
Symbolic Computation
Perform operations on mathematical expressions containing variables without assigning numerical values.
Calculus
Compute derivatives, integrals, limits, Taylor series, and solve differential equations.
Equation Solving
Find analytical solutions for algebraic, trigonometric, and differential equations.
