No. Unity does not use the cosine to calculate dot product. If you look around the internet you can find decompiled unity source files. There you can see that dot product is calculated as follows: dot(a,b) = a.x*b.x + a.y*b.y + a.z*b.z.
I myself use Dot when i need to find the cosine between two vectors. In fact, Angle is defined through the use of Dot.Wed, 25 Apr 2018 19:32:57 GMTbalfire
