Thank you so much! Both of you have done a great job in clearing my doubts away. I will treat them as my primary guidelines when it comes to graph drawing in PA. Oh, just another question here. Is it safe to simply assume that the word ''menjadi'' and ''kepada'' in the petikan means the exact jumlah for something?

For example
''Nilai eksport buah-buahan pada tahun sebelumnya mengalami peningkatan sebanyak 2.3%, atau RM 25 juta  kepada RM 310 juta pada tahun 2012.''
-So, is it safe to right away tabulate RM 310 juta for the category of eksport buah-buahan in year 2012?

I ask this because after I did a few practices, I realised that there were same keywords in the petikan that refers to the exact value for any category in any given year.
*
It's hard to conclude without a proper context, but I think it is a yes. Menjadi means become, and therefore when it says menjadi RM310 it means become RM310.

You are most welcome though. Graph is really interesting and the only fun thing you have in sem 2 PA (dasar sucks).

I forgot to use trigo identities to solve the problem....how dumb am I!
The question that he showed is the one that I am facing right now, I asked teacher and she got stuck halfway too...
RED-HAIR-SHANKS that question is a clone of STPM 2001 question.

I decided to approach it again by using Quotient rule, and this time I think I got it right.

Well, I think you have the solution by now but just out of academic interest, here's how I would go about it.

Note that questions like what RED-HAIR-SHANKS posted do not have a specific way to solve the problem (i.e. they have more than one possible solution). However, it is worth noting that the strategy behind such questions is to use the simplest solution possible (do not try to overthink!), and try to use alternatives if possible, if you are unable to obtain the solution with your method. icon_idea.gif

Just Visiting By, I got a few questions here concerning PA graph:-

1)For the skala in our graph, should we measure it based on 1 cm or 2 cm? I'm more inclined to write, say, ''2 cm: RMXX'', but some of my friends write it as 1 cm instead.

2)When drawing graph garis regardless of graf garis mudah or kompaun, should we draw out different patterns for each of the line? For instance, the first line is just a plain one, while the second is dotted-line, the third consists of thicker line and so forth.

3)When writing down the sumber in our graph, is it a must to include it in a bracket?

4)How do we add the word 'anggaran' where necessary?

As for my PA kerja kursus:-

1)Under the section of Objektif Kajian, how many questions are roughly needed for one objektif? So far I only have 9 and 8 questions in my first and second objektif respectively, are they suffice? Or should I add more?

2)When we're to cite the source and definition of our tema, are we allowed to refer to a webpage? One of my friends from other school informed me that we aren't allowed to cite our source of information based on Wikipedia and the likes. Instead, we should rely on Kamus Dewan when giving out specific definition and explanation under our Pengenalan.

3)Are 30 respondents enough for one kerja kursus? I'm doing 2 different kerja kursus in one go, so I reckon it'll be easier if I were to kill 2 birds with one stone, than having to find 60 respondents in a total. I need some clarification because a handful of my classmates are getting as much as 45 respondents!

I have to complete my PA kerja kursus before the CNY holidays, so time is of the essence now.

Thanks for answering my questions.

As for graphs

1) As far as I remember, I always write 1cm : XX. I cannot recall or remember anyone who use 2cm : XX and I cannot remember whether it is allowed or not. To be safe, use 1cm: XX.

2) There's no need different patterns. In the exam, just use colour pencil to show the different data, and then specify them in petunjuk by drawing a horizontal line of that colour in the box and then state what it is.

3) I can't remember as well, but it seems rather appropriate to include a bracket.

4) The word 'anggaran' is written at the x-axis (below the year your data obtained via estimation) for both bar and line graph.

I can't remember much about the kerja kursus and I believe there are lots of changes since my year, but if I were to answer:
1) It's more than enough. Normally 6 is sufficient.

2) Wikipedia can never be a source or reference in any projects, in all levels and in all places. Dictionary is the best source for definition while certain websites which are official like MPM could be quoted. Bloggers, wikipedia, yahoo which quote source or are not official cannot be used as a reliable source.

3) 30 is the minimum I think, so ya it's sufficient. Why are you doing two different topics anyway?

These are all I can remember. Sorry I couldn't be more helpful.

Oh, but my teacher has been going around saying that labeling the readings of y-axis(regardless of any graph) with a distance of 2 cm apart is fine. I'm a little unsure of myself since I prefer writing down the scale of the graph in 2 cm. I've been using Oxford for my PA, but I noticed that some of the graphs are a bit oddly drawn.

I'm simultaneously doing 2 themes as a fail-safe procedure in case one of my kerja kursus goes awry. I've received many complaints from my ex-senior where they couldn't finish their kerja kursus in time, hence I try to coerce myself to complete one of it before the forthcoming Chinese New Year.

Besides, after we're done with the holidays, we'll immediately move on to our Chemistry coursework. Our teacher also informed us that our initiation of third term Physics coursework(involving interference of sound wave) will be after the CNY holiday, and we're expected to conduct our Physics experiment during the holidays at the beginning of June(right before we officially start third term studies). And let's not forget that we have a Maths T assignment coming right up in this term.

Your y-axis is labelled 2cm apart (one box) but while writing skala you need to make it 1cm: XX (half a box).

Chill. I was there, I know there are lots of projects and assignments to rush but there really is no need to be that rush. It can be done simultaneously, you just need good time management.

Alright, I understand now. Thanks.

Apparently, time management is what I'm bad at. I don't really get it though, I revise for roughly 8 hours per day, rushing through my homework and all and yet I couldn't even graze my friends' academic performances when they claimed that they study less than I do.

I've known a student who was able to score straight A+ in SPM, while at the same time held the position of president in 8 organizations like Scouts, Magazine Editorial Board, Purple Team Captain, just to name a few. She even said that she spend just 3 hours in study and doing homework. This might seem trivial to most of the people out there, but I deeply respect this kind of student. She know her stuffs well.

Just Visiting By, these are the 2 MUET Speaking questions for the first and second group respectively.(Both of them are rephrased, and the choices for each candidates A, B C and D are in random arrangement.)

First group:-
Question in Task A: What is the most important factor that affects your personal success? Give reasons and suggestions to support your answer.
Choices: Family, Friends, Teachers, Co-workers.

Second group;-
Question in Task A: What is the most important place to be improved in your house? Give reasons and suggestions to support your answer.
Choices: Dining room, Relax places, Study room, Bedroom

And again, for this speaking test, I noticed that the question for the second group is generally tougher than the first's, just like last year's test. I strongly believe that the marking scheme for the first group will be more stringent, because 2 of my friends who scored the highest mark in speaking component(39/45) in my class were in the second group with the harder questions.

I've stuck in this question before. Here, let me give you a hint that will kick-start your momentum in solving this question:

Multiply both the LHS and RHS of the equation by user posted image.

I think I know why you're having a trouble with this question because I was having the same problem too. There are possibly many ways for you to solve it, either by multiplying the user posted image into the parentheses, or by using product rule. But, I've done it using both said methods and I still couldn't prove the equation albeit going through a lot of steps. The thing here is that you have to know which is the simplest method that you can execute in order to arrive at the correct solution. chocobo7779 taught me this, and it's called Occam's Razor.
