take the arctangent of a number in php

To take the arctangent of a number in PHP, you can use the atan() function. This function takes a single argument, which is the number for which you want to find the arctangent. The result of the function is the arctangent of the input number in radians.

Here's an example usage of the atan() function:


main.php
<?php
$num = 0.5;
$arcTan = atan($num); // Returns 0.46364760900081

echo "The arctangent of $num is $arcTan radians.";
?>
123 chars
7 lines

This will output:


main.php
The arctangent of 0.5 is 0.46364760900081 radians.
51 chars
2 lines

Note that the atan() function returns the result in radians. If you want the result in degrees, you can use the rad2deg() function to convert the result:


main.php
<?php
$num = 0.5;
$arcTan = atan($num);
$deg = rad2deg($arcTan); // Returns 26.565051177077

echo "The arctangent of $num is $arcTan radians or $deg degrees.";
?>
163 chars
8 lines

This will output:


main.php
The arctangent of 0.5 is 0.46364760900081 radians or 26.565051177077 degrees.
