Deriving integration formulae
Some inquisitive students have asked me before, how the MF15 integration formulas come about. I thought I should share it too then. So we want to and yes, we know the formula can be plugged [...]

Some students complain that they often read a question and cannot figure if there is a conditional probability present. So lets hope the following explanation will aid them to better understand [...]
Many students are stuck when they see something like for example. They are unsure what tto do and some of them attempt to rationalise it. Here’s a little tip to resolving all such [...]
This is question in relation to the birthday paradox we discussed earlier. A room contains randomly chosen people. Assume that a randomly chosen people is equally likely to have been born on any [...]
As I mentioned, a few of my students are planning to enter Math courses in the university post A-levels. They approached me regarding university courses and advices. We shall look at a few local [...]
This is a question taken from the 2008 H1 paper. I think it is a simple question that test students on their understanding of what standard deviation mean. An examination is marked out of 100. It [...]
A man looks at his watch at a random time between mid-day and 1300H. What is the probability that the angle between the hands of the watch is less than ? Ans:
As many students will note, more and more questions these days have the ominous “Hence” word. They can heave a sigh of relief if they still see “or otherwise”. But if it [...]
This is a rather easy questions which stumped a good number of students initially. Hint: You must use integration by parts.
This questions is on vectors, in particular, finding the shortest distance of a point (0, 0, 3) to the plane. My student was able to do it but had a terrible careless mistake. But nevertheless, I [...]
