Classes and their operations

Please be informed of every change that is made to this calculator, many more operations are being added that can help you and an example of use is given.

Basic Operations

• Sum, substract, product, division, module, root, raise to

BasicOperations.sum(2,5,8,4,11) // { result: 30, toNegative: [Function: toNegative] }
BasicOperations.substract(304, 20, 51) // { result: 233, toNegative: [Function: toNegative] }
BasicOperations.product(35,1,9) // { result: 315, toNegative: [Function: toNegative] }
BasicOperations.division(25,5) // 5.00
BasicOperations.module(40,4) // 10.00
BasicOperations.root(1296, 4) // 6
BasicOperations.raiseTo(3, 5) // 243

Base

• binary to base 10, to base

Base.toBase(20, 4) // -> 110
Base.binaryToBase10(1001) // -> 9

Fractions

• Sum, substract, product, division, simplify, destructure

Fractions.sum(1,2,-4,6) // 1/2 + (-4/6)-> -1/6
Fractions.substract(-5,2,4,7) // -5/2 - 4/7 -> -43/14
Fractions.product(10,2,-5,4) // 10/2 * (-5/4) -> -25/4
Fractions.division(5,3,7,2) // (5/3)/(7/2) ->10/21
Fractions.simplify(154, 6) // 77/3
Fractions.destructure("12/5") // { top: '12', bottom: '5' }

Equations

• Secoond degree

// 2x² - 3x + 3 = 0
Equations.secondDegree(2, -3, 3) // Output: { x1: '3/4 + 𝓲√15/4' , x2: '3/4 - 𝓲√15/4'  }

Percentage

• What percentage is, percentage of, percent from percent, total from percent

// What percentaje is 12 out of 30?
Percentage.whatPercentageIs(12, 30) // 40.00%

// How much is 7% of 39?
Percentage.percentageOf(7, 39) // 2.73

// If 30% is 10, then 60% is...
Percentage.percentFromPercent(30, 10, 60) // 20

// If 10% is 20, the total is...
Percentage.totalFromPercent(10, 20) // 200

Rule of three

• Simple

RuleOfThree.simple("direct", 10, undefined, 60, 90) // Output: 15

Triangles

• Functions return information about triangles

Triangles.angle14_76()

/* Output:
{
  hypotenuse: 'k√17',
  opposite: 'k',
  adjacent: '4k',
  sin: 'k/k√17',
  cos: '4k/k√17',
  tan: 'k/4k'
}
*/

Linear Regression

• Simple

var array_x = [100, 90, 80, 45, 50, 50, 60, 40, 25, 20];
var array_y = [3, 5, 9, 10, 20, 21, 24, 24, 27, 35];

console.log(LinearRegression.simple(array_x, array_y));

//Output:
/*
{
  a: -0.34788,
  b: 37.28128,
  equation: '-0.34788x + 37.28128',
  coefficient: [Function: coefficient]
}
*/

Area

• Triangle, rectangle, circle, square, square2, trapeze

// ...
Area.triangle(4, 3) // 6
Area.circle(5) // 25π
// ...

Operations

• Hypotenuse, to romanized, log, factorial, double factorial, combinatorial, fibonacci, divisors

Operations.hypotenuse(7, 9) // -> √11.40
Operations.toRomanized(420); // CDXX

// log5x = 4
Operations.log(5, null, 4) // 625

// 4!
Operations.factorial(4); // 26

// 10!!
Operations.doubleFactorial(10); // 3840

    8, 13, 21, 34, 55, 89,
    144
]
*/

Vectors

• Sum, Substract, Product, unit vector

// (3, 6) + (2, -7)
var vector_a = [3, 6];
var vector_b = [2, -7];

// Sum or sustract returns object
Vectors.sum(vector_a, vector_b)

/*
  {
    x: 5,
    y: -1,
    expression: '5i - 1j',
    cartesian: [ 5, -1 ],
    unit_vector: [ 0.98, -0.19 ]
  }
*/

// (2i - j) • (5i + 2j)
Vectors.product( [2, -1], [5, 2] ) // 8

Vector.unitVector(-3, 5);

System of equations

• Double

var equation1 = [1, 2, 10];
var equation2 = [2, -1, 5]

console.log(SystemEquation.double(equation1, equation2))
// { x: 4, y: 3 }

Chemical elements

• Show, obtain by group, obtain by family

// You can enter the name, symbol, or atomic number of an element to obtain its details, 
// if you do not enter anything it will return the complete list.
ChemicalElements.show("H")

/*

    simbol: 'H',
    atomic_number: 1,
    atomic_mass: 1,
    name: 'Hydrogen',
    group: 'I A',
    type: 'Non-metal',
    electroegativity: 2.2
  }
*/

//  I A, II A, III A, ...
ChemicalElements.obtainByGroup("I B") // object

// You will place the family of the elements you want to obtain
ChemicalElements.obtainByFamily("Halogen") // object

Angle measurements system

• Radian, Centesimal, Sexasegimal (toRadian, toCentesimal, toSexagesimal)

...

// 2π/5
AngleMeasurements.radian("2/5").toCentesimal() // 80

// 40ᵍ
AngleMeasurements.centesimal(40).toRadian() // π/5

// 45°
