So I recently came across the PHP function asinh() and I'm a bit confused about how it works. I've tried looking up documentation online, but I still need some more clarification.
Here's an example of what I'm trying to understand:
$num = 2;
$result = asinh($num);
From what I understand, the asinh() function is used to calculate the inverse hyperbolic sine of a number. In this example, we're passing the number 2 to the asinh() function and then echoing the result.
My question is, what exactly does asinh() do in this case? How does it calculate the inverse hyperbolic sine of 2? I'd appreciate it if someone could break down the process and explain it to me.
Thanks in advance for your help!
