PHP asinh() Function
Definition and UsageThe asinh() function calculates inverse of hyperbolic sine of given parameter. In other words, the return value of asinh() is hyperbolic sine of given parameter. A inverse hyperbolic sine function is defined asasinh(x) = log(x+sqrt(pow(x, 2)+1))This function returns a float value.Syntaxasinh( float $arg ) : floatParametersSr.NoParameter & Description1argA floating point value whose inverse hyperbolic sine is to be calculatedReturn ValuesPHP asinh() function returns inverse hyperbolic sine ratio of given parameter.PHP VersionThis function is available in PHP versions 4.x, PHP 5.x as well as PHP 7.x.Example Live DemoFollowing example calculates asinh(pi/2) which we can verify using the definition −OutputThis will ...
