How to find inverse cos
Hello,
I need to find the inverse cos of -0.25. It's supposed to be 104.478 degrees. ( cos -1 (-0.25) )
When I use Mathf.Acos it returns me different number.
Why is this happening?

It works in Radians, where 2*pi = 360 degrees
If you need to use degrees use this in conjunction
