Upon request by some students, I’ll discuss a few trigonometry formulae here and also some of their uses in A’levels. I’ve previously discussed the use of factor formulae here [...]

Today I’ll share a question that came out of CJC Prelim 2017 Paper 1 for H2 Mathematics 9758. I think some of my student would have seen this question before and we discussed it in class [...]

B6 let Sub to Thus, it is a min point. C7 let (NA). There are no stationary points for this curve. C8 Let Evaluate with a calculator…

Maths notation is often overly complex. Let’s see how this can be better:

This is a pretty cool and interesting question from AMC. There are four lifts in a building. Each makes three stops, which do not have to be on consecutive floors on include the ground floor. For [...]

The positive integers and satisfy What is the value of ?

I came across this interesting algebra/ arithmetic problem the other day. … Do you think this will always work? Hint: We can use algebra to prove this cool sequence easily. Arithmetic [...]
