Package Exports

linear-quadratic-cubic-eq-solver
linear-quadratic-cubic-eq-solver/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (linear-quadratic-cubic-eq-solver) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

functions

This package exposes three different functions:

solveLinearEquation(a, b)

Which is able to solve equations in the form of:

0=ax+b

It returns

[] when there is no solution
[0] when every x is an sulution
[x:number] with the solution

solveQuadraticEquation(a, b, c)

Which is able to solve equations in the form of:

0=ax^2+bx+c

It returns

[x_1:number, x_2:number] or [x_1:Complex, x_2:Complex] with the two solutions
or the return possibilities of solveLinearEquation(a, b) when a == 0

solveCubicEquation(a, b, c, d)

Which is able to solve equations in the form of:

0=ax^3+bx^2+cx+d

It returns

[x_1:number|Complex, x_2:number|Complex, x_3:number|Complex] with the two solutions
or the return possibilities of solveQuadraticEquation(a, b, c) when a == 0
or [0] and the return possibilities of solveQuadraticEquation(a, b, c) when d == 0

Solve an eqaution

To solve an equation like:

4=2*x^2-32*x+2.1

You can use this package like this:

const solver = require('linear-quadratic-cubic-eq-solver');

const solutions = solver.solveQuadraticEquation(2, -32, 2.1 - 4);
console.log('solutions', solutions);

// which returns: solutions [ 16.059156283383516, -0.05915628338351553 ]
