SymPy (Symbolic Python) is a powerful Python library used for symbolic mathematics. It allows you to work with mathematical expressions exactly as written, without numerical approximation.
- Performs exact symbolic computation (not floating-point approximation)
- Supports algebra, calculus, matrices and equation solving
- Useful for students, researchers and data science professionals
Installation
SymPy can be installed using pip on all major operating systems Windows, Linux and MacOS. It requires only Python and has no external dependencies, making setup fast and lightweight.
SymPy Basics
This section introduces the core symbolic concepts used in SymPy. It builds the foundation for performing algebraic and logical computations.
Basic Symbolic Operations
Learn how to define symbols, perform symbolic computations, simplify expressions, substitute values and use basic functions like sin() and factorial() to manipulate mathematical expressions symbolically.
Algebraic Manipulation
Explore how to expand, factor, collect like terms and rationalize algebraic expressions using SymPy’s symbolic engine for simplifying complex formulas.
- Expanding Expressions
- Factoring Expressions
- Collecting Like Terms
