O-Level Additional Math

[YLH88]

Hi achemtutor,


Thank you!

Bounty:

I am back again. Thank you for your all your help.

I have spoken to my daughter’s school Prinicpal. I have the option of doing the subject privately as an additional subject and the school will register her for the O Level exam through the school. This is what MOE also told me.
So now, could anyone recommend me a good teacher who can teach her the complete school curriculum on a one-to-one tuition at home (or any other suggestions)? And the rates of course. I live in Woodlands.

Hi Bounty,

I can give her a try. As a professional math trainer, I look forward to taking the challenge to help every student for a better change.

Some student hate math while others are scary of math. Some seriously lack the background of previous classes while others simply need a change in learning attitude (but making such a change is never simple though). These initial obstacles have to be dealt with before going to the next step which includes strategic theory review and practise questions. What does “strategic” mean? It means 2 things:
(i) most important subjects which carry high mark portions have to be carefully highlighted and addressed
(ii) the preparation need to be individualized to deal with particular background weaknesses of each student.

Indispensably, every student needs to know by heart the tips to identify, analyze a new question as a known question and thinking process to solve it.

Feel free to send your daughter in for a FREE workshop & an assessment test.

woah..... these questions making my head spin already :faint: :faint:

Welcome to the real world mate ! We have no Mohammads and Alis exchanging marbles or silly old mothers trying to pick up their daughters from the schools at constant speed every day here.

How, I wish, school would get easier as we advance in age.....

iFruit:

We just have beautiful x's and y's and before you blink sin As, cos Bs and Sec Cs.

I thought there was sine, cosine, and a tangent???? what's a Sec???

sec A = 1/ cos A ...... (sec is short form for secant)

Hi


Just a quick survey,how do you find secondary one Maths?
Is it less demanding or easier than PSLE Maths?

Best wishes

pls advise where can i get hold of Sec 2math exam papers(express) of top schools. Something like they have for primary school.

You can try Bras Basah Complex. I think there’s a shop that compiles exam papers of top schools and put out for sale.

Plz help!


The scale of map P is 1/p and the scale of map Q is 1/q. Suppose a street is represented by lines of 12cm long and 16cm long on maps P and Q respectively.
a) find p/q and express the answer in the simplest form.
b) if p=5000, find (i) the value of q, (ii) the actual length, in m, of the street.
c) if p=5000 and the actual area of a plot of land in 2812.5metre square, calculate its area on (i) map P and (ii) map Q.

TIA.

Hi

I did some reading using my boy’s textbook and will attempt to answer your question.

a)A scale of 1:p means that 1cm represents pcm
Therefore 12cm represent 12pcm in map P
Likewise, 16cm represent 16qcm in map Q
12p=16q
Hence p/q = 4/3

b)q = 3750
The actual length of the street is 12*5000 = 600m

c)For map P
1cm represents 50m
1 cmsq represents 2500 cmsq
2812.5/2500 = 1.125 cmsq

For map Q
1cm represents 37.5m
1 cmsq represents 1406.25 cmsq
2812.5/1406.25 = 2 cmsq

Are my answers correct?

Best wishes
