Installation

To install WdMath, you can use npm or include the script directly in your project.

npm install wdmath
yarn add wdmath

Usage

Complex Numbers

WdMath provides functions to work with complex numbers, including addition, subtraction, multiplication, and division.

Example:

const complex1 = { real: 1, imag: 2 };
const complex2 = { real: 3, imag: 4 };

const sum = WdMath.addComplex(complex1, complex2);
console.log(sum); // { real: 4, imag: 6 }

Geometry Calculations

Functions to calculate properties of various geometric shapes like cones, cylinders, prisms, pyramids, and spheres.

Example:

const radius = 5;
const height = 10;

const volume = WdMath.cylinderVolume(radius, height);
console.log(volume); // 785.3981633974483

Conversion Utilities

Convert between degrees and radians.

Example:

const degrees = 180;
const radians = WdMath.toRadians(degrees);
console.log(radians); // 3.141592653589793
