A student is applying the Gram-Schmidt process to the basis {v⃗1,v⃗2,v⃗3}\{\vec{v}_1, \vec{v}_2, \vec{v}_3\} of R3\mathbb{R}^3. They have correctly computed the first two orthonormal vectors, u⃗1\vec{u}_1 and u⃗2\vec{u}_2, such that span{v⃗1,v⃗2}=span{u⃗1,u⃗2}\text{span}\{\vec{v}_1, \vec{v}_2\} = \text{span}\{\vec{u}_1, \vec{u}_2\}. What is the correct expression for the third orthogonal (but not yet normalized) vector, w⃗3\vec{w}_3?
