Simple Tips for Better Maths Results!
It is simple to follow the steps of solving a cubic equation which includes finding the linear factor by using calculator and the quadratic factor by long division or comparing coefficient.
However, when the question is asked in another manner in which the solutions are given and the polynomial equation is to be formed. Some students might be at a lost of how to start the question.
I share with you on how we approach this style of question below:
There are two methods to solve exponential equations:
Students must know which method to use when solving an equation. Generally, we take ln on both sides when there is just a single exponential function and we use substitution when there is a common term.
Let's take a look at the examples:
I received this question on finding minimum gradient of a curve and it is confusing for many students as they probably lack the flexibility in seeing gradient beyond dy/dx.
I have presented this question in a slightly different manner by reducing the usage of first derivative (dy/dx) and second derivative (d^2y/dx^2).

After doing the revised syllabus 4047 GCE O-Level Additional Maths Paper 1, it reconfirms that Cambridge is testing basic concepts but presented in a different manner.
There are a few questions which are truly testing your application like the one on quadratic curve is always negative, range of m for which the graphs have two intersection points ...
I highly recommend all candidates to read your question carefully, keep asking yourself if you have answered the question.
An additional point to highlight is look at the allocation of marks to gauge the amount of working to present, the choice of approaches to use.
Based on what have been tested in Paper 1, we are looking forward to the following concepts in Paper 2:
I would be expecting cross-chapters questions on Monday. Just like you, I'm a candidate so the above list is just my suggestion.
All the best for the final Maths paper. See you at the finishing line.
PS: Don't worry about bell curve! It's beyond our control!
I have just completed the 2015 GCE O-Level Elementary Maths 4016 Paper 1 and found it to be more applications based.
Some questions are indirect and required more analysis. Some of the questions I enjoyed doing were:
Once again, just like last year, there are about 2-3 questions which are 5 marks. (If I remembered correctly)
Based on what were tested, we are logically make some guesses of what we are expecting in Paper 2. The following topics are what I'm suggesting and they are for reference only:
Regardless of how you think you have fared for Paper 1, continue to work hard for Paper 2 which is 2 days away. Practice daily!
All the best!
