@yetnt/ump

Useless Math Package

I mean.. Do you really need this soon to be multi mathemetically functioning package? (if that even makes sense)

Installation

npm i @yetnt/ump
sudo npm install @yetnt/ump
yarn add @yetnt/ump

It's suggested you don't install from github itself as I'm consistently commiting to the project you'll need to update everyday and because some code breaks because i'm editing it so just get it from npm 👍

const Ump = require("@yetnt/ump");
Ump.primeFactorize();

or

const { primeFactorize } = require("@yetnt/ump");
primeFactorize();

Features

primeFactorize

Prime Factorization

Parameters

• num: The number to be factorized

const { primeFactorize } = require("@yetnt/ump");

primeFactorize(50); // [2, 5, 5]
primeFactorize(5000); // [2, 2, 2, 5, 5, 5, 5]

Pattterns

The functions stay mostly the same for all the pattern stuff, just with different parameters depending on the pattern.

Linear Patterns

findNthTerm

• num1: The first number in the sequence
• num2: The second number in the sequence
• num3: The third number in the sequence
• returnSimplified(optional): Return the simplified formula of Tn = dn+c rather than Tn = a + (n - 1) * d

findTerm

Find the a term in the sequence.

• n: The term position in the sequence
• d: The difference
• a: First number in sequence. The formula for this is Tn = a + (n - 1) * d. If you prefer to use Tn = dn+c, then a is c

const { LinearPattern } = require("@yetnt/ump");

let nthTerm = LinearPattern.findNthTerm(10, 20, 30);
console.log(nthTerm); // { a: 10, d: 10, formula: '10 + (n - 1) * 10' }
LinearPattern.findTerm(90, nthTerm.d, nthTerm.a);

// USING SIMPLIFIED FORMULA

let nthTerm = LinearPattern.findNthTerm(10, 20, 30, true);
