Mathematics with Computers
[ted id=1007] I want to share this video with students to highlight the importance of learning computing today. Many A-level students do not realise, but their peers in universities (especially [...]

Many students memorise the standard answer, that is, when the estimated data is not within range, we are extrapolating so it is not reliable. But why is it unreliable! Consider an example of [...]
The midyears for many JC have ended and most of my students got their papers back. I notice a handful do not follow instructions very clearly. The instructions to candidates always state clearly [...]
In 2013 A-level Paper 2 , many students made an unfortunate mistake. The following is an snapshot of questions 2 of the paper. Many students faced the dilemma of what to prove, and some resorted [...]
One of the confusing thing that many JC2s stumble upon is that variances in A-levels. This is partly attributed to the lack of understanding and introduction of the concept. By hypothesis [...]
Arthur Benjamin is a brilliant mathematician and calls himself the mathemagician. Yes, he performs magic with mathematics. Magic or not, you decide! [ted id=199]
I’m one who really hates memorizing formulas, be in as a student or tutor. So I shall share how I remember the three very useful trigonometry identities. I’ll start with the one which [...]
The one thing many students overlook in A-level is Time. A lot of students I see lack the ability to finish the full paper on time, that is, in 2.5h, not 3h. We all need to check on the [...]
This is a very old-school and technical method we learnt in secondary school. However, many students are unable to do it accurately still. The trick of completing the square is realising that it [...]
This will be about integrating product of trigonometric functions with no powers involved for example, or . The simple trick here is to use the product to sum to formulas that can be found here. [...]
