Example of Acos function
<?php
echo (acos(0.15)."</br>");
echo (acos(0)."</br>");
echo (acos(1)."</br>");
echo (acos(-1)."</br>");
echo (acos(2)."</br>");
?>
Output
PHP Asin() function
It is used in PHP to find the arcsine of a number as a numeric (value -PI/2 and PI/2 radians).
Syntax
Parameters in Asin function
It contains one parameter.
Parameter |

echo (asin(2)."</br>");
?>
