Definition: The Sinh () PHP function is used to find the hyperbolic sine of the given variable. Sinh (x) would give you the hyperbolic sine of x. It can also be calculated as (exp(x) - exp(-x))/2, with exp being e raised to the power of x.
Also Known As: Hyperbolic Sine
Examples:
<?php
echo(sinh(1) . "<br />");
echo((exp(1) - exp(-1))/2 . "<br />");
echo(sinh(0) . "<br />");
echo(sinh(-1) . "<br />");
?>
This would return the results:
1.1752011936438
