tanh() function in PHP

Thistanh()The function returns the hyperbolic tangent of the specified value.

Syntax

tanh(val)

parameter

• val-radian value

returns

Thistanh()The function returns the hyperbolic tangent of the specified value val.

Example

The following is to get 0 and1Example of the hyperbolic tangent of:

<?php
　　　echo(tanh(0)  .  "<br>");
　　　echo(tanh(1)  .  "<br>");
?>

Output Result

0<br>0.76159415595576<br>

Example

Let's see an example to get the constant M_PI_4Example of the hyperbolic tangent of-

<?php
　　　echo(tanh(M_PI_4));
?>

Output Result

0.65579420263267

Example

Let's look at an example to get the value 0.5and-0.5The hyperbolic tangent of 0-

<?php
　　　echo(tanh(0.50)  .  "<br>");
　　　echo(tanh(-0.50));
?>

Output Result

0.46211715726001<br>-0.46211715726001

Example

Let's look at another example to get the hyperbolic tangent of a negative value-

<?php
　　　echo(tanh(-5)  .  "<br>");
　　　echo(tanh(-10));
?>

Output Result

-0.9999092042626<br>-0.99999999587769
