SUMMARY
The discussion focuses on finding the unit normal vector of two vectors using the cross product method. The user initially calculated the normal vector as i + j + k but questioned whether this vector is a unit vector. It was clarified that the resulting vector is not a unit vector, and the correct unit vector can be derived using the formula \(\hat{n} = \frac{n}{|n|}\), resulting in the unit vector being \((i + j + k) / \sqrt{3}\).
