How do I find an angle between two vectors?
That makes sense. How do we find the magnitudes of the two vectors?
The magnitude of a vector is the square root of the sum of the squares of its components. So for example, if we have vector a = (a1,a2,a3), then its magnitude is |a| = sqrt(a1^2 + a2^2 + a3^2).
