    Completely solve trigonometry equations for angles and sides

    Installation

    Run:

    npm install trigonometry-calculator --save

    Usage

    1. Construct an object mapping angles and sides to their respective objects where the key is a number in the range [0, 3) and the value is the given number.
    2. Pass the object to trigCalculator.
    3. The function will return an object similar to the input except it will include a key-value pair containing the solution with full numerical precision.
    import { trigCalculator } from 'trigonometry-calculator';
    // ES5 / CommonJS require works in addition to ES6 import
    // var calculator = require('trigonometry-calculator');
    // In ES5 call calculator.trigCalculator
    let unsolvedTriangle = {
      angles: { 2: 117 },
      sides: { 0: 6.9, 1: 2.6 }
    };
    console.log(trigCalculator(unsolvedTriangle));
    /*
    {
      angles: { 0: 47.00257739237024, 1: 15.997422607629744, 2: 117 },
      sides: { 0: 6.9, 1: 2.6, 2: 8.405901446641815 }
    }
    */
     
    // If there is an alternate solution due to ambiguity that will be solved as well
    unsolvedTriangle = {
      angles: { 1: 31 },
      sides: { 1: 8, 2: 13 }
    };
    console.log(trigCalculator(unsolvedTriangle));

        sides: { 0: 6.764779420434399, 1: 8, 2: 13 }
