JavaScript - Math.sin in degrees

0 contributions
5 points

In JavaScript Math.sin() method works using radians by default. To switch it to degrees some simple operation is necessary ((Math.PI / 180) * degrees). In this article we can see custom Math.sin() function that works on degrees.

// ONLINE-RUNNER:browser;

function calculateSine(deg) {
	var radians = (Math.PI / 180) * deg;
  	return Math.sin(radians);

// Example:

console.log( calculateSine(0)   ); //  0
console.log( calculateSine(30)  ); // ~0.5
console.log( calculateSine(45)  ); //  0.7071067811865475
console.log( calculateSine(60)  ); //  0.8660254037844386
console.log( calculateSine(90)  ); //  1

console.log( calculateSine(180) ); // ~0
console.log( calculateSine(270) ); // -1
console.log( calculateSine(360) ); // ~0
