Find the acute inclination of the reflected ray to the -axis when is inclined at to the -axis and to the -axis.

I meant to share more on factor Formulae today. However, a few students are not so sure how to get the R-formulae correctly during their preliminary exams recently. So I thought that I’ll [...]

Here is another question that is from CJC H2 Mathematics 9758 Prelim Paper 1. Its a question on differentiation. I think it is simple enough and tests student on their thinking comprehension [...]

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 [...]

[email protected] is a series of questions that we, as tutors feel that are useful in helping students think and improve their understanding. Thinking [email protected] is curated by KS. More of [...]

I’ve covered some things in classes, with sufficient revisions and final lap papers set. So I thought we have a little breakdown. And of course, we should review what was weeded away in the [...]

Here is a compilation of all the trigonometry articles KS has done. Students should read them when they are free to improve their mathematics skills. They will come in handy! 🙂 1. How to derive [...]

Trigonometric functions can be difficult to handle. So here is some intuition and idea on what to do when dealing with certain trigonometric functions. Integrating Trigonometric Function #1 [...]
