What is Math.sin () in JavaScript? The Math.sin () method in Javascript is used to return the sine of a number. Math.abs (-5.4); returns 5.4 - Math.sin (): As the name implies, this method allows you to calculate the sine of different angles, and the value that can be seen in the result is between -1 and 1. You can use a function like this to do the conversion: function toDegrees (angle) { return angle * (180 / Math.PI); } Note that functions like sin, cos, and so on do not return angles, they take angles as input. Math.abs (-6.8); returns 6.8. So, let's say that we have an angle we know to be in degrees: double inDegrees = 30; We first need to convert it to radians: double inRadians = Math.toRadians(inDegrees); And then we can calculate the sine value: double sine = Math.sin(inRadians); Math.sign() Returns the sign of the x, indicating whether x is positive, negative, or zero. - JavaScript Maths Functions: Math.round() The Math.round() or Math.round(x), evaluates to a value closest to an .
