Chapter 9.4, Problem 1E

A vector in three dimensions can be written in either of two forms: in coordinate form as $v=\langle a_1,a_2,a_3\rangle$ and in terms of the _________ vectors $i,j,$ and $k$ as $v=$ __________. The magnitude of the vector $v$ is $\left|v\right|=$ _________. So $\langle 4,-2,4\rangle =\boxed{}i+\boxed{}j+\boxed{}k$ and $7j-24k=\langle \boxed{},\boxed{},\boxed{}\rangle$.
