OMG! I had a bad time typing equations in microsoft word... just so mafan and hard to type. Someone guide me with it!

Anyways, I hope the solution below is correct.

PS: Your recent posted image is not the same as the one you give initially. The 2nd one is definite integration... this one is indefinite.

Added on November 3, 2008, 12:37 am@Shenay,

I'm not getting the same answer as the solution posted btw... for step 2 I get:

2 [ (x^2 - x^3) / ( 3(1-3x) ) ]

Intergration must expand it wad..
U dun expand cant do..

Not necessary, if the equation is up to a power of 3 and more how are you going to expand? It's going to be a hella long to do that.

there is a formula for this particular case.

I don't think you can do that
Lets say integrate 2x-3x2

Your method
2x-3x2
= x(2-3x)
= (x2/2)(2x- 3x2/2)
= x3 - 3x4/4

Correct method
2x-3x2
= x2 - x3
*
I didn't get x3 - 3x4/4

instead i get x2 - x3

You can directly integrate the x2 - x3

and no, you cannot remove x as a common factor. why? because you are integrating dx. if you do that, meaning x is take out of the integration, in the end, you still have x.


-------------

raptor_cZn,

You can try expanding the equation and then integrate it. It comes to the same as mine. And yes, it's under our syllabus to take the whole bracket as one whole thing and integrate it. Alternatively, you represent

1-3x = u
1/u2

or something like tat.

Added on November 3, 2008, 6:56 amOh ya, to add,

for thins like

(3-1x)3

there is a formula for this.

(ax-b)n+1 / (dy(ax-b)/dx * n+1)

Meaning, I should get:

(3-1x)4/(-1 * 4)
(3-1x)4/-4

Please check your book in reference to this. I'm not using anything out of syllabus.

Zzz.... please read my equations closely. Since when did I factorise the x out? I'm doing the normal way.

Either way, from my friends, point of view, there is no solution for this equation. It is not possible to integrate as the combination of nominator and denominator especially when the denominator is powered by 2.

You can integrate them

3x²+2x+15
--------------
  (1+3x)²

// = integrate

seperate them [//3x^2 / (1+3x)²] + [//2x / (1+3x)²] + [//15 / (1+3x)²]
*
Nope, can't integrate anything like tat. No formula for SPM level yawn.gif

Radiation is simple to understand. Only a few formulas there and some basic facts. Keep practicing and you'll eventually get it.
And don't get nuclear fusion & fission mixed up. =D

For the probability distribution, are you referring to:
e.g. P(Z>0.5), P(Z<0.5), P(Z<-0.5)?

I think you mean Radioactivity, not radiation smile.gif. Radiation is heat transfer.

@aad_lfcfn,

It already started with diploid, meaning 2n = number of chromosomes. The haploid is divided by half then. That means the 4 daughter cells after the whole process of meiosis 1 and 2 will produce 4 daughter cells with haploid chromosome numbers.

Added on November 4, 2008, 6:51 amNote: You mentioned prophase 1, meaning the chromosomes haven't separate to become haploid yet.

given a geometric progression x -1 , 10, 3x + 2, p ...., express p in terms of x
*
10/x-4 = r ---- 1
p/3x+2 = r ---- 2

sub 1--2

30x+20 / (x-1) = p

nvm i figured out adi ;D just like what IamjustME say,refer to the arrow in the question.
1 more question,do i need to label those A,B,C,D,E,F ?label also no marks one right ?
*
Must label. Even the length given in the questions, must label. There is even a method to label. That means, it shall not be neglected.

all my teachers who were marking for spm papers agree with this ...

the way they answered the question  just like they knew what questions gonna ask in spm especially in sejarah

iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii

just some common tips for spm

. pencil is allowed as long as the words written are readable ...but beware , spm papers are marking by examiners in their house ... who knows their son rub off ur answer ?( my stupid scenario lol)

liquid paper correction pen also dangerous , some cheap azz ink gonna  be transparent after few days ...
when the words covered by liquid paper is visible again ...those words u written on top of it are unreadable when examiner is marking it , so just 0 mark

tie the extra papers inside the booklet ..not in last page

tabulate data .... must draw table ... the line must draw completely ( the test pad does have horizontal line but u needed to draw on the top of the printed horizontal line or it would not consider as ur table )

point forms are allowed in essay section except for BM BI Sejarah
last thing , do ur best , try to get A ... study  2 years for  SPM now is the time ...
*
Don't take the risk, don't use pencil. Cancel it nicely.

Also, who said we could use Liquid/Correction Pen in SPM O.o. I went and check the rules and regulations again stated in the SPM TimeTable. It was clearly stated, no liquid paper.

@skzisghost,

1 huraian for 1 isi. and 1 cth. That would work for every paragraph.

Correction tape and liquid paper are 2 different things. I used correction tape during PMR and had no problems.

Its function is the same. Read closely:

Ya i understand.. but that is how it is understood and written in the rules and regulation. Worst come to worst, I would say is moral, whereby the essay paper, you cannot ask for more paper.

Ya, what I mean is SPM is your future here as a Malaysian. PMR you get T/D also nobody cares.

Added on November 5, 2008, 11:35 pm@vick5821,

Here's your hint to solve:

S4 = 24
--- what do you understand by this? What is the formula for Sum of terms?

T1 + T3 + T5 + T7 + T9 = 55

---

It should be substitution method.
