JavaScript method atan()
This section illustrates you the use of JavaScript method atan(). The atan() method returns the arc tangent of a specified number as a numeric value between -PI/2 and PI/2 radians. You can see in the given example that we have used the method atan() and want to find out the arc tangent of 2. We have created a button which calls the function calculate() from the script and displays the output.
Here is the code:
| <html> <script> function calculate(){ document.write("The value of atan(2) is: "+Math.atan(2)); } </script> <h2>Use of atan() method</h2> <button onclick="calculate();">Use of method atan</button> </body> </html> |
Output will be displayed as:
On clicking the button, you will get the arc tangent of 2:
