The following are a list of A-levels topics in H2 Mathematics. I’ve added what I feel is the hardest part of each topic amongst students. Functions: Finding the range of a composite Curve [...]
This is a very theoretical question with regards to hypothesis testing. My student asked what is meant by 1% level of significance. So I know that many would have memorised the standard format of [...]
Here, we shall discuss something called the Triangle inequality which states that . I thought this is rather important as I see too many students writing things like latex |2+(-2)| = 0latex [...]
So now let us look at a simple relationship that many students memorise instead of understand. Below, we see a absolute function graph. Now we all know that gives us . So how did that happen? [...]
I notice many students forget how discriminant works! I think I should inform A-level students that they need to know how it works and that is one thing they should not return to their O-level [...]
