WebI'm adapting my answer on Stack Overflow.. 2D case. Just like the dot product is proportional to the cosine of the angle, the determinant is proprortional to its sine. And if you know the cosine and the sine, then you can compute the angle. Many programming languages provide a function atan2 for this purpose, e.g.:. dot = x1*x2 + y1*y2 # dot … WebJan 31, 2014 · I understand that: atan2(vector.y, vector.x) = the angle between the vector and the X axis.
