I am SURE this question has been asked before. But searches only found me dead links. D:

I want to find the slope of a Vector between two points in 3D space (p1 and p2)

This works:

```
var slope = Mathf.Atan( Mathf.Abs(p1.y - p2.y) / Mathf.Abs( p1.magnitude - p2.magnitude) ) * Mathf.Rad2Deg;
```

I am looking for a more computationally efficient method. I assume one of the Vector3 functions does this much faster.

Thanks for any hints!
