Mathematics for IGCSE & O level - Vectors (Section 2 - No. 13)
In a triangle, \(\vec{AB} = \vec{p}\) and \(\vec{BC} = \vec{q}\). What is the value of \(\vec{AC}\)?
\(\vec{p} - \vec{q}\)
\(\vec{p} + \vec{q}\)
\(\vec{q} - \vec{p}\)
\(2\vec{p} + 2\vec{q}\)
설명
Using the triangle rule, AC = AB + BC, hence AC = p + q
