JavaScript SIN

by

The JavaScript Sin function is a Math function that calculates the Trigonometry Sine for the specified expression. The syntax of the JavaScript Sin Function:

Math.sin(number);

The JS Sine function returns the value between -1 and 1. The mathematical formula of the Javascript Trigonometry Sine function:

SIN(x) = Length of the Opposite Side / Length of the Hypotenuse

JavaScript SIN Function Example

In this JS SIN example, we are going to find the Sine values of different data types and display the output

TIP: Please refer JavaScript ASIN Function to find the Arc Sine.

OUTPUT

JavaScript SIN Function

ANALYSIS

We tried JS SIN Function on the string value. It will return NaN (Not a Number)

document.getElementById("Str").innerHTML = Math.sin("JavaScript");

Next, we tried SIN() Function on Null value, and it returns Zero as output

document.getElementById("Null").innerHTML = Math.sin(null);

In the below statement, We used the SIN Function on multiple values.

document.getElementById("Multi").innerHTML = Math.sin(25 + 55 - 77);
