JavaScript Math sin() method example

Here, we will understand sin() method through various examples.

Example 1

Let's see a simple example of sin() method.

<script>
document.writeln(Math.sin(1)+"<br>");
document.writeln(Math.sin(2));
</script>
Test it Now

Output:

0.8414709848078965
0.9092974268256817

Example 2

In this example, we will use sin() method with negative numbers.

<script>
document.writeln(Math.sin(-1)+"<br>");
document.writeln(Math.sin(-0.5));
</script>
Test it Now

Output:

-0.8414709848078965
-0.479425538604203

Example 3

Let's see sin() method with some different test cases.

<script>
document.writeln(Math.sin(0)+"<br>");
document.writeln(Math.sin(Math.PI));
</script>
Test it Now

Output:

0
1.2246467991473532e-16

Example 4

Here, you can test sin() method with your own test cases.

<script>
function display()
{
  var x=document.getElementById("num").value;
document.getElementById("result").innerHTML=Math.sin(x);
}
</script>
<form>
  Enter a number: <input type="text" id="num">
  <input type="button"  onclick="display()" value="submit">
  </form>
  <p><span id="result"></span></p>
