Question

Which of the following represents vector u = −3i + 8j in component form?

Answer 1

Solution

- The way to write vectors in component form is given below:

$\begin{gathered} u=u_xi+u_yj \\ \text{ In Component form, we have:} \\ u=\langle u_x,u_y\rangle \end{gathered}$

- Thus, we can apply the rule stated above to the question given to us.

- This is done below:

$\begin{gathered} u=-3i+8j \\ \\ \therefore u=\langle-3,8\rangle \end{gathered}$

Final Answer

The answer is

$u=\langle-3,8\rangle\text{ (OPTION 2)}$
