Answer
$\langle -4.1042,11.2763 \rangle$
Work Step by Step
Horizontal component of $\textbf{u}=12\cos110^{\circ}$
Ensuring that the calculator is in degrees, we type $12\cos110$ into the calculator and solve:
$12\cos110^{\circ}=-4.1042$
Vertical component of $\textbf{u}=12\sin110^{\circ}$
Ensuring that the calculator is in degrees, we type $12\sin110$ into the calculator and solve:
$12\sin110^{\circ}=11.2763$
Therefore, $\textbf{u}=\langle -4.1042,11.2763 \rangle$
