Benchmark: Quick Sin Cos vs Math Sin Cos

Script Preparation code:

let factorialize = function (num) {
    if (num === 0 || num === 1)
        return 1;
    for (let i = num - 1; i >= 1; i--) {
        num *= i;
    }
    return num;
}

let FACT_2 = 1 / factorialize(2);
let FACT_3 = 1 / factorialize(3);
let FACT_4 = 1 / factorialize(4);
let FACT_5 = 1 / factorialize(5);
let FACT_6 = 1 / factorialize(6);
let FACT_7 = 1 / factorialize(7);

const HALF_PI = Math.PI * 0.5;

var mysin = function (angle)
{
    let pow2 = angle * angle;
    let pow4 = pow2 * pow2;
    let pow6 = pow4 * pow2;
    return 1 - pow2 * FACT_2 + pow4 * FACT_4 - pow6 * FACT_6;
}

var mycos = function (angle)
{
    return mysin(angle + HALF_PI);
}
