Now I know this is one known fact that students just accept. Why is it that anything raised to the power of 0 is 1? We know that , meaning we take the 2 and multiply it three times. So [...]

Now, we all know that every single formulas from vectors, or simply turn to that huge mind-map or thick notes we have. The other day, I asked my class the following: All of you know how to find [...]

As we all know, the Ratio Theorem is given in MF15. But some students struggle to fit in the and every time. They will then attempt to draw a bit and see it helps. Here’s a solution for [...]

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 [...]

, and go to a party. and are partying away but is miserable and anti social. and go up to and say ‘what’s wrong, why don’t you integrate?’ replied, It doesn’t make [...]

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 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. [...]
