Find the projection of $\mathbf{v}=2 \mathbf{i}+\mathbf{j}-3 \mathbf{k}$ onto $\mathbf{u}=-\mathbf{i}+\mathbf{j}+\mathbf{k}$
Find the projection of u onto v. Then write $u$ as the sum of two orthogonal vectors, one of which is proj, u. $$\begin{aligned} &\mathbf{u}=\langle 4,2\rangle\\ &\mathbf{v}=\langle 1,-2\rangle \end{aligned}$$
