The missing solution

b ii) Let the diameter of the semicircle PQR = d

Then, d = d_{1}+ d_{2}+ d_{3}…….. d_{n} x π

π d = πd_{1}+ πd_{2}+ πd_{3}…….. πd_{n} ÷ 2

π d/2 = πd_{1}/2 + πd_{2}/2 + πd_{3}/2 …….. πd_{n}/2

Length of the arc of the outer semicircle = length of arcs of the inner semicircle 1

+ length of arcs of the inner semicircle 1

+ length of arcs of the inner semicircle 1

+ ……+ length of arcs of the inner semicircle n

c) For any value for the outer semicircle, it depends on the diameter of the circle. Therefore, the generalization from bii) it true for every value of the diameter so that the length of the outer semicircle is the same with the total length of the inner circle

nvm you're tried. 有心了~~~

its ok sir....ur teaching is enough for the 'project'

owhhh no.....i dun hv any tips rte nw.....damn....nwy thnx 4 trying sir...

The Add Maths Project~

teacher told us to do edi`

I nid ur help edi`teacher`

Thank you, sir.

for the add maths project.

but my school teacher haven't told us anything.

anyway,

THANK YOU once again. ☺

excuse me the equation i received is the cacat one but i have microsoft 2007 .. so how?

Sam HelLow

Mayb you try to see the equation carefully, because like dy/dx it looks a bit weird when you look at it. Or try to get the file from your friend

All the best

wt a good newz..... but for no unknown reason my beloved +math teacher dun want it in com typing!!! bcoz if do so the whole class will have the same "product"... so IT MUST BE IN HAND_WRITING!!! i wish u could do it 4 me due to the MALASnism... gurau je lah... anyway thnks sir i tabik spring at u!!

If only I have your brain!!! then I don't have to worry about my SPM!!. I don't even have any clue what formula to use when I first read the question...nope..I don't even understand the language used!!

Thank you very much!!! This will be the first time I pass up my project before the closing date!according to the format, we're supposed to include conclusion and discussion sections that is a summary of the equations we did.

but how do we do that?

For conclusion, discussion, summary You have to do yourself because difference school has difference ways to do, you have to ask your teacher for confirmation

All the best

My teacher want it in Mathematical equation but yours aren't. How to change it with my Microsoft word 2007?

Click "insert", then click "object" then search for "Microsoft Equation". Then u can type in equation form

Sir Sir~~~

the part2 (a) ya,

ask us to complete table tat one...

see the 3rd column~

y the answer is 10π der??

formula for circuference is 2πr ma...

since it is a semicircle,

den the formula is πr only lor...

since the d is 10cm, den the r should be 5cm lor...

so arc length = πr = 5π lo....

why put 10π der~? 0.0

or my formula wrong edi~??

reply fast o sir...

gonna pass up 3days later ><

kakakakaka

ur student~

Pls look up at the table, i typed "divide 2"

I means, every number i put in the table have to divide by 2

Ok?

oh~

so i din put (diveid by 2),

the answer all cut half oso can lor?

hehehe

thank you la leng zai~

sir, about the missing solution:

c) For any value for the outer semicircle, it depends on the diameter of the circle. Therefore, the generalization from bii) it true for every value of the diameter so that the length of the outer semicircle

Question: is this sentence complete or theres something else?

thx sir...

it's really help me alot...^_^

Hey sir its Jim from last year Perfection Kota Damansara just stopping by to say hello.. And uh, my A-levels physics teacher is a woman and she is so boring!! And she teaches like a maths teacher.. Aww i miss ur teaching.

Sir Loke, can you post the tips for SPM 2009??

(physics or other subjects) CAN??

sir spm tips for physics please..:)

teacher, u know the new add maths project 2010?

hi...hihi

any information for me to solve this problem,my school teacher din give us anything!!!!i dunno how to do?

can u help me?

thanks

teacher how 2 type in equation form?

where 2 find "insert"?bcoz i'm computer baichi
