linear-equations
About linear-equations
linear-equations is a mathematical Python module providing Linear Equations in one variable, and Linear Equations in two variables as Python objects through two classes called LinearEquation1D
and LinearEquation2D
.
Date of creation: April 04, 2021
Date of first release on PyPI: April 29, 2021
Along with the classes describing algebra of linear equations, a class Symbol
has also been provided to allocate the symbols used in these equations.
gui-linear-equations
A small graphical-user interface based program is also available as a sub-part of this project. The GUI version of linear-equations has a dependency on this module, linear_equations
.

Some features and functionalities
- class
Symbol
symbols to use in Linear Equations, for example: Symbol("x") -> x
- class
LinearEquation1D
objects of type
ax + b = 0
- class
LinearEquation2D
objects of type
ax + by + c = 0
- function
solve1D(eqn)
used to retrieve the solution to a 1D equation
- function
solve2D(eqn1, eqn2)
used to retrieve solution to two 2D equations
- function
consistency(eqn1, eqn2)
checks and returns if the given LinearEquation2D objects are consistent or not
- function
satisfies(eqn, x, y)
returns True if the given pair of numbers satisfy a particular LinearEquation2D and False otherwise
All classes, methods and functions are enriched with help-text that can be acccessed using the following syntax:
help(linear_equations.thing)
Edit the logging settings
To modify the level of the logger
, modify:
logging.basicConfig(
filename="linear-equations.log", level=logging.INFO, format=LOG_FORMAT
)
on Line 102 of gui_linear_equations.py
to:
logging.basicConfig(
filename="linear-equations.log", level=LEVEL, format=LOG_FORMAT
)
where LEVEL
can be one of:
logging.INFO
logging.DEBUG
logging.WARNING
logging.ERROR
logging.CRITICAL
Update History
Update (0.0.5)
Added graphing and visualization of 2-dimensional equations.
Added function graph(eqn1, eqn2)
which graphs the given LinearEquation2D
objects on a 2D mathematical plot along with their solution (if any)
Update (0.0.6)
Minor bug fixes:
- Fixed issues with plotting linear equations
- Improved legend on graphs
Added function graph_many(eqn1, eqn2, ..., eqn, show_legend=True)
which graphs more than two LinearEquation2D
objects on the same plot along with each of their solutions (if any)
Updates (0.0.7)
Minor bug fixes
Footnotes
'gui_linear_equations.py' makes use of global variables.
