I'm currently working on a project that involves some mathematical calculations, and I came across the PHP `asin()` function. I'm not quite sure how it works and what its purpose is, so I was hoping someone could help me understand it better.
To give you some context, I'm developing a web application where users can input different types of data, including angles. I need to be able to calculate the arcsine of certain angles, but I'm not sure how to do that using PHP.
I've heard that the `asin()` function in PHP can help with this, but I'm not familiar with its syntax or how to use it properly. If someone could provide me with an example of how to use the `asin()` function and explain how it works, I would greatly appreciate it.
Thanks in advance for your help!
