### Why

Because I've lately started to think a little more functional, this also allows for nice chaining of calls to the Math class.### How to use

Say you want to calculate the angle between 2 vectors by taking arc cosine of our dot product to give us the angle:With normal Math usage..

var dot = vector1.X* vector2.X + vector1.Y * vector2.Y + vector1.Z * vector2.Z; double radians = Math.Acos(dot);Same example with our extensions

var dot = vector1.X* vector2.X + vector1.Y * vector2.Y + vector1.Z * vector2.Z; double radians = dot.Acos();

The above example but with a method to calculate the dot product.

double radians = vector1.Dot(vector2).Acos();

Quite a lot of overloads, I think I got them all but if you find that I've missed one, please comment on this post and I will add it!

All code provided as-is. This is copied from my own code-base, May need some additional programming to work. Use for whatever you want, how you want! If you find this helpful, please leave a comment, not required but appreciated! :)

Hope this helps someone out there!
