For example, the function appears in math as math.sin, acting on a single number. It also appears in numpy as numpy.sin, where it can act on vectors and arrays in one go. sympy re-implements many mathematical functions, for example as sympy.sin, which can act on abstract (sympy) variables.

SymPy is an open source computer algebra system written in pure Python. It is built with a focus on extensibility and ease of use, through both interactive and programmatic applications.

>>> from sympy.physics.units import convert_to >>> convert_to (q, day) 71.5112118495813*pi*day >>> convert_to (q, day). n 224.659097795948*day We could also have the solar mass and the day as units coming from the astrophysical system, but we wanted to show how to create a unit that one needs. SymPy examples. GitHub Gist: instantly share code, notes, and snippets.

SymPy includes features ranging from basic symbolic arithmetic to calculus, algebra, discrete mathematics and quantum physics. It is capable of showing results in LaTeX. $ pip install sympy SymPy is installed with pip install sympy command. Rational values. SymPy has Rational for working with rational numbers. A rational number is any number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q. SymPy Goal Goal Provide a symbolic manipulation library in Python. \SymPy is an open source Python library for symbolic mathematics. It aims to become a full-featured computer algebra system (CAS) while keeping the code as simple as possible in order to be comprehensible and easily extensible. SymPy is written entirely in
