26-27 Express the vector v as the sum of a vector parallel to b and a vector orthogonal to b. \text { (b) } \mathbf{v}=3 \mathbf{i}+\mathbf{j}-2 \mathbf{k}, \mathbf{b}=2 \mathbf{i}-\mathbf{k} \text

{ 26. (a) } \mathbf{v}=2 \mathbf{i}-4 \mathbf{j}, \mathbf{b}=\mathbf{i}+\mathbf{j} (\mathrm{c}) \mathrm{y}=4 \mathbf{i}-2 \mathbf{j}+6 \mathbf{k}, \mathbf{b}=-2 \mathbf{i}+\mathbf{j}-3 \mathbf{k}
