Quote of the day
Many who have had an opportunity of knowing any more about mathematics confuse it with arithmetic, and consider it an arid science. In reality, however, it is a science which requires a great amount of imagination.
(Sofia Kovalevskaya, 18501891)

Kevin, Excellent idea. In fact, I was working on that the past few weeks and was hoping to release it before this May IB exam session but did not manage. Hope to do so soon.

Hi Tim, Are your accessible to discriminating questions available as one file? They'd be very good for making a revision document that touches on all topics.

I read what you said again, I understand the ambiguity you were talking about.

Tim thank you for your speedy reply. I would say if the question is reworded like you say, then I agree that the answer is 278degrees but the original wording suggests that the answer is different. The bearing of X from a lighthouse is different...

Michael, The syllabus for each new course is in the respective Subject Guide available in the Programme Resource Centre (PRC) on the MyIB site. This Math HLSL site will evolve into a new site for the Analysis & Approaches course, while the...

Hi! Can you post new syllabus for Applications and Interpretations here please?

Omolade, In Q.3 the bearing of 278 degrees given in the solution is the direction one would travel from X to Y; hence, it is the bearing of Y from X. So, it is correctly stated in the question and in the solution. I do think that the wording...

Question 3: the bearing answer is the bearing of X from Y.

Hi Joya, Thanks for query. The new site (for which I will be editor) for the new Analysis & Approaches site will be available to all subscribers next month. This site will have thorough updates for the new Analysis course.

HI garry . how do we contact you in order to suggest updates . Regards JL

Hi Tim: Thank you for your time! Turns out I had copied the problem down incorrectly :). Best, Beth

Beth, Thanks for your query. I have posted a worked solution for the accessible HL Q1 above (it's below discriminating HL Q3). You'll need to click on the 'eye' to reveal the solution. I hope it helps.
