PHP sinh() Function

PHP sinh() function is used to find the hyperbolic sine of the given input angle value. The hyperbolic sine of any argument X is equal to “(exp(X) – exp(-X))/2”. Here exp() is the exponential function which returns e raised to the power of argument passed to it. It accepts only a single parameter $number that is the number whose hyperbolic sine value is to be found. Its value must be in radians.

Syntax:

  sinh($number);

Parameter Values

Parameter Description
number This is a required parameter. This parameter defines the number passed as argument.

Here is an example of sinh() function in PHP:

<html>
<body>

<?php

echo sinh(0)."<br>";
echo sinh(1)."<br>";
echo sinh(1.5)."<br>";
echo sinh(2)."<br>";

?>

</body>
</html>
Output:
0

2.1292794550948
3.626860407847

Here is another example of sinh() function in PHP:

<html>
<body>

<?php

echo sinh(0)."<br>";
echo sinh(pi()/2)."<br>";
echo sinh(pi()/4)."<br>";
echo sinh(pi()/6)."<br>";
echo sinh((3*M_PI)/2)."<br>";

?>

</body>
</html>
Output:
