## Exam Style Question## Worked solutions to typical exam type questions that you can reveal gradually |

Question id: 3. This question is similar to one that appeared in an IB Standard paper in 2010. The use of a calculator is allowed.

If \(f(x)=xsinx\), for \(-3\le x\le3\)

(a) Find \(f'(x)\)

(b) Sketch the graph of \(y=f'(x)\), for \(-3\le x\le3\)

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. |
