SUMMARY
The discussion focuses on the orthogonal projection of the vector x = <0, 10, 0> onto the plane spanned by the vectors v1 = <4, 3, 0> and v2 = <0, 0, 1>. The participant utilized the cross product to find the normal vector k = v1 x v2 = <3, -4, 0> and calculated the projection p = <-4.8, 6.4, 0>. The final step involved verifying the correctness of the projection by ensuring that the vector (x - p) lies in the plane and is perpendicular to p, confirming the solution's validity through dot product checks.
