JavaScript ASIN

by

The JavaScript ASIN function is one of the JavaScript Math function which is used to calculate the trigonometry Arc Sine for the specified expression. Arc Sine is also called as inverse of a Sine, Please refer JavaScript SIN Function article to understand the Sine Function. In this article we will show you, How to use ASIN() function in JavaScript Programming language with example.

Syntax of a JavaScript ASIN Function

The basic syntax of the JavaScript ASIN Function is as shown below:

Math.asin(number);

Number: It can be a number or a valid numerical expression for which you want to find Arc Sine value.

  • If the number argument is positive or negative number, ASIN() function will return the Arc Sine value.
  • If the number argument is not a number, ASIN() function will return NaN.
  • If the number argument is outside the range -1 and 1, ASIN() function will return NaN.

JavaScript ASIN Function Example

The JavaScript ASIN Function allows you to find the trigonometric Arc Sine for the numeric values. In this example, We are going to find the Arc Sine values of different data types and display the output

JAVASCRIPT CODE

<!DOCTYPE html>
<html>
<head>
    <title> JavaScript ASIN Function </title>
</head>
<body>
  <h1> JavaScript ASIN Function </h1>
  <p id = "Pos"></p>
  <p id = "Neg"></p>
  <p id = "Dec"></p>
  <p id = "Neg_Dec"></p>
  <p id = "Str"></p>
  <p id = "Exp"></p>
  <p id = "Null"></p>
  <p id = "Multi"></p>
  <p id = "Out"></p>
  <script>
    document.getElementById("Pos").innerHTML = Math.asin(1);
    document.getElementById("Neg").innerHTML = Math.asin(-1);
    document.getElementById("Dec").innerHTML = Math.asin(0.45);
    document.getElementById("Neg_Dec").innerHTML = Math.asin(-0.75);
    document.getElementById("Str").innerHTML = Math.asin("JavaScript");
    document.getElementById("Null").innerHTML = Math.asin(null);
    document.getElementById("Multi").innerHTML = Math.asin(0.25 + 0.55 - 0.77);
    document.getElementById("Out").innerHTML = Math.asin(25);
  </script>
</body>
</html>

OUTPUT

JavaScript ASIN Function

ANALYSIS

First, We used the ASIN() Function directly on both the Positive integer and negative integer.

 document.getElementById("Pos").innerHTML = Math.asin(1);
 document.getElementById("Neg").innerHTML = Math.asin(-1);

Next, We used the ASIN() Function on both the Positive and negative Decimal values. If you observe the above screenshot, ASIN() function will work perfectly with decimal values as well

 document.getElementById("Dec").innerHTML = Math.asin(0.45);
 document.getElementById("Neg_Dec").innerHTML = Math.asin(-0.75);

Next, We tried ASIN() Function on String value. As we said before, this will return NaN (Not a Number) as output

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

Next, We tried ASIN() Function on Null value and it return Zero as output

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

In the below statement, We used the ASIN() Function directly on multiple values.

document.getElementById("Multi").innerHTML = Math.asin(0.25 + 0.55 - 0.77);

Last, We used the ASIN() Function on the Positive integer which is greater than one. As we said before, this will return NaN (Not a Number) as output

document.getElementById("Out").innerHTML = Math.asin(25);
