The Math.sin() static method returns the sine of a number in radians.
function getCircleY(radians, radius) {
return Math.sin(radians) * radius;
}
console.log(getCircleY(1, 10));
// Expected output: 8.414709848078965
console.log(getCircleY(2, 10));
// Expected output: 9.092974268256818
console.log(getCircleY(Math.PI, 10));
// Expected output: 1.2246467991473533e-15
x
A number representing an angle in radians.
The sine of x, between -1 and 1, inclusive. If x is Infinity, -Infinity, or NaN, returns NaN.
Because sin() is a static method of Math, you always use it as Math.sin(), rather than as a method of a Math object you created (Math is not a constructor).
Math.sin(-Infinity); // NaN
Math.sin(-0); // -0
Math.sin(0); // 0
Math.sin(1); // 0.8414709848078965
Math.sin(Math.PI / 2); // 1
Math.sin(Infinity); // NaN
