Solving Equations
In this lesson, we will learn about solving different types of equations numerically and symbolically.
SymPy has equation solvers that can handle linear and non-linear algebraic equations as well as linear and non-linear multivariate equations. Depending upon the input equation, the answer returned can be symbolic or numeric. The most commonly used one is solve()
. It uses the following syntax:
solve(f(x), x)
The output type of solve()
varies with input, sometimes it returns a Python list and sometimes a Python dictionary. Usually, for single variable equations, it returns a list and for multivariable equations, it returns a dictionary.
Let’s explore different cases in the examples below:
Solving for a single variable
Single solution
Let’s solve the following equation that has a single solution:
