Exam-Style Question on Vectors
A mathematics exam-style question with a worked solution that can be revealed gradually
Question id: 44. This question is similar to one that appeared on a IGCSE Extended paper in 2005. The use of a calculator is allowed.
ABCDOE is a regular hexagon with O as origin. The position vector of A is \(a\) and the position vector of B is \(b\).
Find the following in terms of \(a\) and \(b\).
(c) the position vector of C.
If the sides of the hexagon are each of length 10cm calculate:
(d) the size of angle \(BCD\).
(e) the area of triangle \(BCD\).
(f) the length of the line from B to D.
(g) the area of the hexagon.
The worked solutions to these exam-style questions are only available to those who have a Transum Subscription.
Subscribers can drag down the panel to reveal the solution line by line. This is a very helpful strategy for the student who does not know how to do the question but given a clue, a peep at the beginnings of a method, they may be able to make progress themselves.
This could be a great resource for a teacher using a projector or for a parent helping their child work through the solution to this question. The worked solutions also contain screen shots (where needed) of the step by step calculator procedures.
A subscription also opens up the answers to all of the other online exercises, puzzles and lesson starters on Transum Mathematics and provides an ad-free browsing experience.
