Say I have point A (20,20) and point B (60,60).
The resulting vector would be 40, 40. How could I get the angle of this vector?
By this I mean, imagine there is an imaginary circle around the origin.
I guess sort of what atan2 does but without atan2.
Thank
I’m not sure what you mean by angle, since you only give one vector in your example. But, given two vectors, you can find the angle between them like so:
Given vectors a and b, normalize both of them. Then, dot(a, b) = cos(θ), where θ is the angle between the two vectors. Use arccos to find θ.
