Mathematics for IGCSE & O level - Vectors (Section 1 - No. 10)
If \(\vec{p} = \begin{pmatrix} 3 \\ 0 \end{pmatrix}\) and \(\vec{q} = \begin{pmatrix} 0 \\ 4 \end{pmatrix}\), then what is \(\vec{p} + \vec{q}\) ?
\(\begin{pmatrix} 3 \\ 4 \end{pmatrix}\)
\(\begin{pmatrix} 0 \\ 0 \end{pmatrix}\)
\(\begin{pmatrix} 3 \\ -4 \end{pmatrix}\)
\(\begin{pmatrix} -3 \\ 4 \end{pmatrix}\)
Selitys
p+q = \(\begin{pmatrix} 3 \\ 0 \end{pmatrix}\) + \(\begin{pmatrix} 0 \\ 4 \end{pmatrix}\) = \(\begin{pmatrix} 3 \\ 4 \end{pmatrix}\)
