Mathematics for IGCSE & O level - Vectors (Section 1 - No. 13)
Given the points A(1, 2) and B(4, 6), what is the vector \(\vec{AB}\) represented as a column vector?
\(\begin{pmatrix} 3 \\ 4 \end{pmatrix}\)
\(\begin{pmatrix} 5 \\ 8 \end{pmatrix}\)
\(\begin{pmatrix} -3 \\ -4 \end{pmatrix}\)
\(\begin{pmatrix} 4 \\ 3 \end{pmatrix}\)
คำอธิบาย
\(\vec{AB}\) = B - A = (4-1, 6-2) = (3,4). This is \(\begin{pmatrix} 3 \\ 4 \end{pmatrix}\)
