JavaScript ASIN

by

The JavaScript ASIN function is a Math function that calculates the trigonometry Arc Sine for the specified expression. Arc Sine also called the inverse of a SINE Function. The syntax of the JavaScript ASIN Function is

Math.asin(number);

If the number arg is not a number or outside the range -1 and 1, the JS ASIN function will return NaN.

JavaScript ASIN Function Example

In this example, We are going to find the JavaScript Arc Sine values of different data types and display the output

<!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

ASIN Function on the string value will return NaN (Not a Number)

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

ASIN Math function on Null value returns Zero as output

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

Last, We used the ASIN Function on the Positive integer which is greater than one. It returns NaN

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