DIRAC'S THEOREM - PROOF BY MATHEMATICAL INDUCTION

A proof by mathematical induction. Dedicated to my IB students of TCSH
Thanks to my IB students at TCSH

This proof is dedicated to all of you, an inspiration that comes from our math lessons together. 
I have looked into some books and internet sources and so far the proof uses the approach of a supposition of a longest path.

I welcome you all to study the proof by mathematical induction given here and tell me if I overlooked something. 

This is one way how you can do a math exploration.

Please click here for the proof.

A proof of CEVA'S & MENELAUS'S theorems without using triangles.
Both proofs use one property where fractions are equal as given below.
(a/p) = (b/q) = (c/r) = ... = (a + b + c+ ...)/(p + q + r + ...)

STPM Trial Exam Paper 2013


STPM Further Math Trial Exam Paper 1 - 2013

STPM Further Math Trial Exam Paper 1 - 2013 - Solution

I feel it is not practical to have students travel to Penang to take the trial exam for Further Math. Two main reasons are:
1. It will take too much time to travel. for those who are too far from Penang.
2. The cost in travelling and accommodation should not be just to take the test.

I promise to set a trial paper for students taking STPM Further Math 2013 - Paper 1. Please help inform that the trial exam paper is posted here. I hope students find this paper beneficial and provide a good guide for them to study. I think include almost everything in the syllabus.

If anyone can find a  hotel to sponsor a seminar room and accommodation then we can have a seminar to discuss the solutions and make preparation for the coming STPM Further Math Paper

Best regards from me.

Teaching Mathematics

Teaching Mathematics In the Higher Forms

Teaching geometric progression offers opportunities to talk about the "wonders" compound interest, how money doubles at 10% every 7 years. Details on saving regularly every month for 10 years and the stop completely can result in more money being saved for a life-time if the same amount is saved every month but starting 10 years late.

Teaching definitions using one word helps many students understand definitions such as
logarithm, weight, center of gravity, standard deviation, half-life, light years etc. Of course some definitions can be taught in this manner. eg What is force? What is calculus?

Examination questions on mathematics make teacher spent much time teaching skills in calculation and concepts and methods. If questions in mathematics more space for matters related to say health issues, environment, borrowing money etc, I believe teachers will also devote time on these areas.
