I and my life

2010-12-05T12:52:00.003+08:00

For the past week,i don't know why suddenly images of my grandpa streamed across my mind.he's gone since 2005 but well i cannot forget the memories i spend with him,i don't know why,it seems that he was an enforcer to my life.He instruct me,taught me and from young educate me to who i am today.I miss him more then anyone else.He's gone and the memories are stuck forever inside it cannot and will not be erased.He is my one and only grandpa,now i can only see him in my dream.Well but better to not be able to see,at least he cherished me.=D.dote on me,caned me for good sake.He taught me how to be cheerful,that's why i am always cheerful even though i might be sad within.He told me,ben you have only this one and only life,i would rather you leave it happily then living it with regrets.With that,i obviously grew into a greenhorn.But well he showed me what is like to be having something yet it turned into memories.Grandpa,i love you.

Ok.It is november and i am bored.So well let me talk about my life.I've just been through the o levels,one of the most fundamental exams in singapore and well obviously i yearn for good results.=D.But sometimes in life,we don't get what we want.For example,in love you may not get what you really want and in return get even more criticisms and nasty comments.But let us all wait and see,time will tell everything unless you are dead the next day.=D.People,they are friendly,some are cruel,cunning.Different people from different walks of life,the think differently,speak differently,play differently.So please respect their views and stfu.=D.Thank you very much.I seriously cannot stand this kind of situations.AAAAAAAA.BYE!

At first,we went to eat pepper lunch with my buddies.The food was really tasty and irresistable..Yummy.One word DELICIOUS!haha.Secondly,Went to check lam's house today with lucas,tuck seng,louis and a unexpected visitor...Cheong how kit.Today is a really enjoyable day,we played blackjack and big two at check lam's house.Lol how kit was a pro blogger....haha.He did a lot of blogging man..very cool check it out here is the link:www.simeon06.blogspot.com
Haha,check lam's sister was so afraid of how kit as he was always standing at the kitchen haha.Haha i aslo dont know why after kelvin chen beat him up,he had some mental problems.i fell really sorry for him man...so poor thing...
Lucas just started plaing today and was quite a good player..
Not bad for a beginner...
Lol

Hi kinda bored so decided to write.

2009-02-21T20:29:00.005+08:00

Well hello guys,
I am still being tortured by that stupid wound..even though it is not itchy,but it is really very irritating...the stupid bandage..
Well i hope i get well...The entire 4n1 is very kind and helpful except someone...that keep on laughing at me,never sympathise never mind..Dont Add salt to pepper please.I hope that person will change for the better and not laughing for the sake of it.It is really not funny when someone is injured...i just notice that actually my class was so united..i really feel so touched..i receive calls from lucas,ting xin,tuck seng,lucas,jeffrey asking whether i am fine..martin wu pan and my other friends,helped me to the general office..,Some of them,even they cannot contact me,use msn and the maths blog to ask about me..My class was so united for the first time =DD..it would be great..Like what martin got from the internet..UNITED WE STAY,DIVIDED WE FALL.Special thanks to All that helped in a way or another..Thank you.Usman i wont blame you...so dont worry...and sorry..i sabo u in front of mr rangen...really sorry
Hope manchester united will win tonight..agianst blackburn....2-0 my predictions..

I have posted the General Cambridge Ordinary and normal level involving the people in 4n1,class of 2009.Please go and check it out,remember the formulas and their marking scheme,so that you can score.They do not put the syllabus there for fun,Please go and check it out.

....xDDDDDD HAHAHA Good luck,hope to see you guys in 5n1 next year hahaa...lol some of you maybe going to ite ... just do not fail your english.Well....looking forwards to the n and o level.
With regards,

Georgraphy test

2009-02-10T20:24:00.003+08:00

mr lim told me that....the workheet very important......this is an inference that shows me....the seq will come out on chapter 10.........i guess the question will be..............what are some of the stratagies to unleviate unven development....??describe u should ..
The total marks allocated is 20.

question 6 i finally figured it out with a little help from bjorn and louis

2009-02-08T20:50:00.002+08:00

Ok since it is the end of the day,i finally solved it here it is.
^_^
6)dy/dx(ax+b/x^2)=a-2b/x^3
sub x=3,y=5 into this equation,it will give you 27a+b=45-eqn1
dy/dx=0,sub x=3,to give u equation 27a-2b=0-eqn2
Solve the equations simultaniousely to give you
A=10/9 and B=15.

Geography Elective homework

2009-02-08T15:58:00.002+08:00

1)erosion,deposition and transportation.

2)energy

3)vegetation,permeability of rocks,climate and drainage basin.

4)gradient,roughness of channel or wetted perimeter.

5)hydraulic action,corrasion,attrition and solution

6)traction,saltation,suspension and solution

7)The hjulstrom curve states that as the higher the energy,the more fast deposition,erosion and transportation can take place.An example is particles of more then the size 0f 10 milimetres like the boulders,need a speed of 100cm/s.However,particles like clay need a speed of lesser then 100cm/s. So,this states that if the energy of the river is lesser like in the lower course, it takes more time to erode,deposit and transport the materials,thus forming landforms like deltas and floodplains.However in the upper course it takes a faster time to erode,deposit and transport,so the fluvial processes are dependent on the energy of the river.

8)upper course-v shaped, middle course u shape and lower course flat shaped.

9)Upper course-waterfall,gorge and v-shaped valley
Middle course-meanders, u -shaped valley and oxbow lake.
Lower course-flat floored valley, floodplains,meanders,oxbow lake and deltas
Waterfall is a vertical flow of fast flowing water.
Gorge is a deep,narrowed and steep sided valley.
V-shaped valley,is formed by vertical erosion,it means a low area between hills or moutains
Meanders are curves and bend along the river.
Oxbow lake is formed by meanders that become very distinct.
U-shaped valley are formed by lateral erosion,so it is wider then the upper course.
Flat floored valley is wider then middle course as it has a low energy,thus forming a flat floored
valley.
Floodplains are formed by the depositions of materials.
Delta is the accumulation of sediments at the river mouth.

So lonely in the skies of me..

2009-02-07T13:37:00.001+08:00

look at the first video in the video bar for those who understand hokkien...lol its really funny...

yay qns 10 down..

2009-02-07T13:09:00.000+08:00

10a)dy/dx,using product rule,should give you 4x(x-2)(x-1)

10b)dy/dx=0,sub x=0,2,1 into x^2(x-2)^2, so it should give you the points (0,0),(1,1)and(2,0)

10c)Here is my reason..Do not copy if you think it is wrong!
As the points (2,0) and (0,0) are on the x axis, it is the minimum point
As the point (1,1) is above the x-axis it is the maximum point.

BY Benjamin pang .

qns 7,8,9....left 6 and 10...

2009-02-06T23:50:00.000+08:00

7a)using product rule to find dy/dx will give you 5(x-2)^3(x-2/5),so when dy/dx=0,x=2 or x=2/5.As x increase through 2/5, dy/dx change from positive to negative.so,2/5 is the max point.As x increase through 2,dy/dx change from negative to positive,so 2 is the min point.

7b)using product rule,to find dy/dx will give you 4(x-3)^2)(x-3/4), so when dy/dx=0 x=3 or x=3/4. As x increases through 3/4...dy/dx change from negative to positive, therefore it is the min point.As x increase through 3 dy/dx > or equal to o,hence 3 is the stationery point of inflexion.

8)dy/dx(x^2-4x+6)=2x-4
2x=4,x=2.subx=2, into(x^2-4x+6),y=2
a=(2,2).As x increases through 2,dy/dx changes from negative to positive, so it is the minimum point.

9a)dy/dx(2x^3-9x^2+12x-4)=6x^2-18x+12
=6(x-1)(x-2) (shown)

9b)dy/dx=0,when x=1,y=1. when x=2,y=0

9c)As x increases through 1,dy/dx changes from positive to negative,so (1,1)is the max point.
As x increases through 2,dy/dx changes from negative to positive,so(2,0)is the min point

Legend:max point=maximum point, min point=minimum point ..hope this will help u all in the homework

clues for qn 4,5 mdm lo part 2..

2009-02-06T23:02:00.000+08:00

here it is...qns4,5,
4a)dy/dx=-3/(x-1)^2

b)X is not equal to 1,(x-1)^2>0,therefore,dy/dx<0.no stationery points.

5a)agian using the quotient rule,u should be able to get the answer,dy/dx=-2(x-1)(x-4)/(x^2-4)^2.

5b)dy/dx=0,x=1 or x=4.

mdm lo for some reasons i could not send it to guru,here is it as requested

2009-02-06T22:51:00.002+08:00

clue for qns 1,2,3
1a]dy/dx=using the normal differenation, it should give u the answer 3x^2-12x

1b]dy/dx=0,firstly simplify 3x^2-12 will give you 3(x-4)=x=0 or x=4

2a)dy/dx 2x-1/x^2+2.using quotient rule it should give you -2(x-2)(x+1)/(x^2+2)^2

2b)dy/dx=0,-2x^2+2x+4=(x+1)(-2x+4),x=-1 or x=2.

3a)using product rule,dy/dx=3(x+3)/2(x+7)^1/2

3b)dy/dx=0 3(x+3),when expanded gives 3x+9=0,thus x=-3
