I prepared super simple example to calculate sin in degrees in JavaScript and decided to share with others. So in order to use this example we just need to change value of deg variable to some other value (in degrees).

// ONLINE-RUNNER:browser;

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

var deg = 30;
var y = calculateSin(deg);

// sin(30 deg) = 0.49999999999999994
console.log('cos(' + deg + ' deg) = ' + y);

We can change deg to other valus. Examples of common calculations:

sin(0 deg) = 0
sin(15 deg) = 0.25881904510252074
sin(30 deg) = 0.49999999999999994
sin(45 deg) = 0.7071067811865475
sin(60 deg) = 0.8660254037844386
sin(90 deg) = 1

I prepated similar post but for calculation cos in degrees:
