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.
So you also knew about Occam's Razor. It is the mentality thing. sweat.gif

Most Malaysian students are taught to work out the given problem directly, without recognizing the root of the problem and find a workaround to it. chocobo7779's method was commendable. icon_rolleyes.gif

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 don't really think it is more stringent for the first group. I think it simply is 'relaxed' or 'lenient' for the second when it is supposed to be as as stringent as the first.

But anyway I am not a marker, I can't really tell for sure.

I have to admit the questions are interesting though. Most important place to be improved? Come on, I can choose any place I want, I can't possibly be limited to the ones given to me lol

My friend who was chosen for the second group(2nd question) told me that all 3 of the candidates had a hard time elaborating and substantiating their given choices in Task A, save for the candidate C whose choice was study room. He said that when they arrived at Task B, all 4 of them were hogging on the third choice, study room, possibly due to it's primary function being related to student's academic performances. One has to be very versatile and creative in answering and discussing this type of questions with fellow candidates. I mean, it's good that they're able to come to a conclusion without having to have any disagreement, but I do hope that it ain't monotonous.

Anyway, I need some clarification here about my Dapatan Kajian in PA kerja kursus.

After all of our questionnaires have been answered, we should plot a table and draw a pie chart based on the umur of our responden, right? So, do we still need to do a short summary on the percentage of our respondents' age after that? For example: ''Berdasarkan hasil tinjauan, umur responden yang terbanyak adalah antara 30 hingga 39 tahun, iaitu 42% (13 orang) daripada keseluruhan.'', or ''Bilangan responden yang terendah ditinjau ialah responden yang berumur 60 tahun dan ke atas, iaitu hanya 3 orang sahaja.'' Are they acceptable?

Next, I've been informed that we should tabulate our data and draw a graph based on the data collected from our soalan. My question is, do we need to tabulate a table, draw a graph, and make a short summary or elaboration on the data that we got from the responden based on every single soalan? Suppose that I have a total of 9 soalan in both of my objektif kajian, in the end, I ought to tabulate and draw 18 tables, 18 graphs, and 18 huraian based on the data of our soalan from all those 30 responden?

My PA teacher has been MIA recently because he wasn't feeling well, so he is unable to be at school for days and I can't do it all by myself without any guide. I need your aid and I'm running out of time. Thanks in advance.

I can relate to the problem because my MUET question was tough as well. I still remember the question:
"The importance of newspaper in our lives"
Candidate A: Report news
Candidate B: Impart knowledge
Candidate C: Improve language proficiency
Candidate D: Advertise products

and I was candidate D. Imagine that. Haha

Anyway for MUET task B, group discussion, it is not necessary that all candidates reach a consensus. You can conclude by saying there are three or four best choices. There need not be an agreement to the question.

As for PA, I think it is alright to write the summary you quoted. I can't help much regarding the graph drawing and summary without any examples. Would you list some of your soalan?

I can't help but find it weird considering the fact that the choice given to candidate D is always the most trickiest choice out of the 4 candidates, most of the times I believe.

As for PA kerja kursus,

Objektif Kajian: Sebab-sebab menyambut perayaan Dong Zhi
Bil.|Soalan.|
1. Hari untuk menghapuskan syaitan
2. Meraikan kedatangan musim sejuk
3. Peringatan jasa Zhang Zhong Jing, seorang tabib Cina
4. ....
5. ..

Each of the above soalan is followed by a score range from 1 to 5. 1=Sangat setuju, 2=Setuju, 3=Tidak pasti, 4=Tidak setuju, 5=Sangat tidak setuju. After we've tabulated our data, we will draw a graph for each question and from there, we will analyze and make a small huraian.

If I were to make a short huraian based on any one of the soalan above, say, for the first question(Hari untuk menghapuskan syaitan). I'd write it like this: ''Terdapat 8 orang(23%) memilih kategori sangat setuju sebagai sebab untuk menyambut perayaan Dong Zhi bagi punca ini. Bagi kategori yang setuju adalah terbanyak, iaitu 13 orang(37%) dan kategori yang terendah adalah sangat tidak setuju, kerana tiada responden yang memilih kategori tersebut(0%)..... And of course, all those percentages and bilangan responden that I've stated in my previous huraian should be based on the graph that I've drawn after I refer to the score for my first soalan(Hari untuk menghapuskan syaitan).

Is this the correct way to hurai my Dapatan Kajian?

Krevaki, can you help me with my Chemistry quiz?

Q1)Explain why methylhydrazine and dinitrogen tetroxide are used as rocket fuels in space flights.

Q2)The solubility of calcium chloride in water is much higher than that of calcium fluoride at 20℃. Explain the difference. [4 m]

For Q1)
-I initially intended to state that both of those substances mentioned above are safer and can cause less pollution. But after I did a little searching in the internet I found out that methylhydrazine is highly toxic, flammable and corrosive whereas dinitrogen tetroxide is a liquefied, corrosive gas.
-Can I simply state that both of these substances can form a hypergolic mixture, with methylhydrazine being the fuel and dinitrogen tetroxide being the oxidizer?

For Q2)
-Generally, the solubility of an ionic solid in a water is affected by 2 factors, the lattice energy of the compound, and the enthalpy of hydration of it's ions.
-An ionic compound is soluble if it's enthalpy of hydration is -ve(exothermic process), meaning that the hydration energy must be greater than it's lattice energy for an ionic compound to be soluble in water.
-Lattice energy is inversely proportional to the ionic radii. The Cl ion in the calcium chloride has a bigger ionic size compared to the F ion in the calcium fluoride.
-This means that the lattice energy in calcium chloride is lower than that of calcium fluoride. But the problem is, how should I link this information with the question since it's stated that CaCl₂ is more soluble than CaF₂ at 20℃?

Yes it is a correct way to explain your data. You can also include some hypothesis. For example Kebanyakan orang menyokong idea ini. Ini mungkin kerana idea ini paling efektif dalam membasmi masalah ini.

I actually thought it would be an easier project if you have learn to convert non-linear to linear, which is something you'll only learn in term 3.

Oh, really? I've thought about that before, but I've no idea whether it'll be accepted into my explanation in Dapatan Kajian. I'll talk about it with my PA teacher.

We haven't been exposed to the conversion of non-linear to linear text, because so far all we learn in this term is mainly about converting linear text to non-linear. Out of curiosity, which is harder?

Linear to non-linear is harder because while drawing graph, you have got too much things to consider and the price of one mistake is very heavy.

Non-linear to linear is easy because while converting the data, you are not limited by number of words to be written and hence you can write as much as possible regardless whether it is correct or not. The calculation is straightforward as the data are all given in a table, all you have to do is to find the trend (which increases most sharply and which difference is largest e.t.c) and then you write them in your words. Simple.

Oh, I always thought it's the other way around, because I find it quite troubling to form a sentence or two based on the data given.

But, regarding the bolded statement above, isn't there any deduction in our marks if we were to falsely interpret the data given?

Correction: 'whether it fits the questions or not'. Sorry.

If the question asks you to compare yearly performance but you write both yearly and monthly performance comparison, there would be no deduction in marks.

However, a mistake in calculation would constitute a failure to read the data and would therefore be penalised.

I see, thanks for explaining all these to me. But, now that I'm in second term, I reckon I'll just leave the third term PA studies aside.

Another quick question: When drawing PA graph, is it reasonable to allot 1 row on the top of the graph paper for the title and 3 rows at the bottom for the skala, petunjuk and sumber? I'm so sorry if I'm being skeptical, but I need to clear as many doubts as I can.

Actually that's what I did too! Haha

You are free to arrange your data anyway you like in the given graph paper provided the size is reasonable.

Thanks once again, I'm gonna need all the luck and time that I can muster for my PA kerja kursus.

I'm nearly halfway done with my first kerja kursus(about adat resam). All that's left is a little tweak here and there in my abstrak, pengenalan, lokasi kajian and kaedah kajian. I don't know if I'm able to complete my Dapatan Kajian before the CNY holiday commence, because the notion of drawing 30 graphs, pie charts and tables is really foreboding.

Just a question here: Can I state two locations for the PA project, so that I can do comparisons?

PS: Recently I burn midnight oil because of my PA teacher who keeps chasing us for all the parts of the project. She always chase us for our work even before the deadline she had given to us. As a result? I kept burning midnight oil for 2 weeks consecutively, and I got bedridden. Yet she still pursued me for the work. I wonder how could I pull through this. sad.gif
