PHP acosh() Function – Inverse Hyperbolic Cosine
This article explains the PHP acosh() function, describing its purpose, parameter and return value, and provides example code demonstrating how to compute the inverse hyperbolic cosine of various numbers with the resulting outputs.
The acosh() function in PHP returns the inverse hyperbolic cosine (area hyperbolic cosine) of a given float argument.
Signature: float acosh(float $arg) Parameter: $arg – the value whose inverse hyperbolic cosine is to be calculated.
Return value: The inverse hyperbolic cosine of $arg expressed in radians.
Example:
<?php
echo acosh(7);
echo acosh(56);
echo acosh(2.45);
?>Output:
2.6339157938496
4.7184191423729
