## Example

In this example we will get the tangent of different numbers:

<script type="text/javascript"> document.write(Math.tan(0.50) + "<br />");
document.write(Math.tan(-0.50) + "<br />");
document.write(Math.tan(5) + "<br />");
document.write(Math.tan(10) + "<br />");
document.write(Math.tan(-5) + "<br />");
document.write(Math.tan(-10)); </script> |

The output of the code above will be:

0.5463024898437905
-0.5463024898437905
