ENG

A module that allows you to solve quadratic and linear equations.

How to use?

Importing

First, import the equation_maths_helper module.

import equation_maths_helper

For convenience, we recommend importing all necessary methods from the module at once.

from equation_maths_helper import linear_one_variable, quadratic

The linear_one_variable method

The linear_one_variable method allows you to solve linear equations with a single variable.

The method accepts the coefficients a and b from the formula ax + b = 0. It also has an additional solution parameter, which is responsible for outputting a step-by-step solution to the console. By default it is set to False. The method returns False if it fails (there are no roots), the root of the equation, or True if the root is any number.

Example of using the method:

from equation_maths_helper import linear_one_variable
equation_answer = linear_one_variable(a=1, b=1, solution=True)
print(equation_answer)

Output the solution to the console:

Root: x = -b / a = x = 1 / 1 = 1.0.
1.0

The quadratic method

The quadratic method allows you to solve quadratic equations.

The method accepts the coefficients a, b, and c from the formula a(x ** 2) + bx + c = 0. It also has an additional parameter solution, which is responsible for displaying the step-by-step solution on the console. By default, it is set to False. The method returns False if it fails (no roots) or a tuple with 1 or 2 roots of the equation.

An example of using the method:

from equation_maths_helper import quadratic
equation_answer = quadratic(a=1, b=1, c=1, solution=True)
print(equation_answer)

Output of the solution to the console:

Discriminant: (b ** 2) - 4 * a * c = (-5 ** 2) - 4 * 1 * 6 = 1.
First root: x1 = (-b - sqrt(d)) / 2 * a = (5 - 1.0) / 2 * 1 = 2.0.
Second root: x2 = (-b + sqrt(d)) / 2 * a = (5 + 1.0) / 2 * 1 = 3.0.
Roots: 2.0, 3.0.
(2.0, 3.0)

Как использовать?

Импорт

Первым делом импортируйте модуль equation_maths_helper.

import equation_maths_helper

Для удобства рекомендуем сразу импортировать все необходимые методы из модуля.

from equation_maths_helper import linear_one_variable, quadratic

Метод linear_one_variable

Метод linear_one_variable позволяет решать линейные уравнения с одной переменной.

Метод принимает коэффициенты a и b из формулы ax + b = 0. Также у него есть дополнитеьный параметр solution, который отвечает за вывод пошагового решения на консоль. По умолчанию он равен False. Метод возвращает False в случае неудачи(нет корней), корень уравнения или True, если корень любое число.

Пример использования метода:

from equation_maths_helper import linear_one_variable
equation_answer = linear_one_variable(a=1, b=1, solution=True)
print(equation_answer)

Вывод решения на консоль:

Root:  x = -b / a = x = 1 / 1 = 1.0.
1.0

Метод quadratic

Метод quadratic позваоляет решать квадратные уравнения.

Метод принимает коэффициенты a, b и c из формулы a(x ** 2) + bx + c = 0. У него тоже есть дополнитеьный параметр solution, который отвечает за вывод пошагового решения на консоль. По умолчанию он равен False. Метод возвращает False в случае неудачи(нет корней) или кортеж с 1 или 2 корнями уравнения.

Пример использования метода:

from equation_maths_helper import quadratic
equation_answer = quadratic(a=1, b=1, c=1, solution=True)
print(equation_answer)

Вывод решения на консоль:

Discriminant: (b ** 2) - 4 * a * c = (-5 ** 2) - 4 * 1 * 6 = 1.
First root: x1 = (-b - sqrt(d)) / 2 * a = (5 - 1.0) / 2 * 1 = 2.0.
Second root: x2 = (-b + sqrt(d)) / 2 * a = (5 + 1.0) / 2 * 1 = 3.0.
Roots: 2.0, 3.0.
(2.0, 3.0)
