Mathematics for IGCSE & O level - Vectors (Section 2 - No. 5)
In triangle ABC, given that \(\vec{AB} = \vec{p}\) and \(\vec{BC} = \vec{q}\), express \(\vec{AC}\) in terms of \(\vec{p}\) and \(\vec{q}\).
\(\vec{p} - \vec{q}\)
\(\vec{p} + \vec{q}\)
\(\vec{q} - \vec{p}\)
\(2\vec{p} + \vec{q}\)
Förklaring
Using the triangle law of vector addition: \(\vec{AC} = \vec{AB} + \vec{BC} = \vec{p} + \vec{q}\).
