Hi all,

Understand that students from IP schools might be expected to do more challenging Mathematics questions compared to O level students.

We would like to try to support them. You can post your questions here and we will try to get our teachers to answer.

Cheers!

Hi there

Thanks for this link.
What assessment book would u offer for sec 1 math?
Thank you.

Hi Future Academy, Like MyPoppy, I was wondering if there is any material u would recommend, just to work e brain muscles? Thanks in advance.

Hi Future Academy,
Dc is doing Accelerated Maths on top of Year 1 IP Maths. Like MyPoppy, I was wondering if there is any material u would recommend, just to work e brain muscles? Thanks in advance.

Hi MyPoppy and minecrafter,

Thanks for your question.

IP school syllabi are different from main stream schools.

Normally the students mainly use notes and worksheets given by the school. In our tuition centre, we also have our own resources, prepared by our tutors who are very experienced in teaching IP school students, in coaching students. We do not use any assessment book in particular.

You cannot really find a single assessment book in the market which is very suitable. I would recommend students to do practice questions in the textbooks recommended by school. Though IP school teachers do not use textbooks in teaching, there might be times that they select questions from the textbooks to assign as homework. Students can try rest of the questions as self practice.

If you know a specific topic/area that your child needs more practice questions, please let me which grade (e.g. Year 1) and which topic/area, I will try to recommend an assessment book, just for that particular topic, to you.

Hi, I have a question on logarithm.

How to do this question? Can someone help?

Show that a^x = e^(xlna).

Thanks!!

Hi Siling,

Let y = a^x
ln y = ln(a^x) [take ln on both sides of the equation]
ln y = x lna [apply power law, i.e. ln (a^n) = n lna]
y = e^xlna. [change the previous equation into the exponential form]
Therefore, a^x = e^(xlna) (shown)

The information inside the [ ] is the explanation of the working. You are not expected to present all these when you are answering the question in exam.
Hope it helps. Cheers!

By the way, I am a former RGS teacher. Feel free to ask me IP Math/Physics questions. =)

Understood.
Tks!

Hi, I have a question here:

Given that sin(A-B)/cos(A+B) = 1/3[tan(A-B)],
(i) show that the value of tanAtanB = -1/2
(ii) find the values of cosB if sinA = 1/2

Hi, just saw your post. sorry for the late reply.

here is the solution:


Please let me know if you have further question.

Cheers!!

the information inside the square bracket [ ] explains the approach.

students are not expected to present all these in exam.

Cheers!
