SymPy offers several ways to solve linear and nonlinear equations and systems of equations. Of course, these functions do not always succeed in finding closed-form exact solutions. In this case, we can fall back to numerical solvers and obtain approximate solutions.
How to do it...
- Let's define a few symbols:
>>> from sympy import * init_printing() >>> var('x y z a')
- We use the
