This tool defines relations that all high school and college students would recognize as mathematical equations. They consist of a left hand side (lhs) and a right hand side (rhs) connected by the relation operator "=".
This tool applies operations to both sides of the equation simultaneously, just
as students are taught to do when
attempting to isolate (solve for) a variable. Thus the statement
yields a new equation
Equation.lhs/b = Equation.rhs/b
The intent is to allow using the mathematical tools in SymPy to rearrange equations and perform algebra in a stepwise fashion using as close to standard mathematical notation as possible. In this way more people can successfully perform algebraic rearrangements without stumbling over missed details such as a negative sign. This mimics the capabilities available in SageMath and Maxima, but can be installed in a generic python environment.
Once the algebra is complete it is possible to substitute numbers with units into the solved equation to calculate a numerical solution with proper units.
Setup/Installation: Use pip to install in your python environment:
python pip -U Algebra_with_SymPy To use in a running python session issue
the following command :
from algebra_with_sympy import *.
This will also import the SymPy tools. If you want to isolate this tool
from the global namespace you are working with change the import statement
import algebra_with_sympy as spa, where
spa stands for "SymPy Algebra". Then all calls would be made to
Usage examples can be found in the docstrings and the demonstration Jupyter
