  Hahahaha, I think they drew the graph for some guy by the name of david? HAHA I can't remember, or John. Okay that's not the main point. ANYWAY! They asked for his speed from home to sports complex. Which is from the graph, calculated speed is 24km/h.

  Next question, they give 1 paragraph on how Sally? Jane? What'shername? started travelling only at 0850 in a car with a speed of 60km/h then reaching home at 1030. They already gave the speed so you need to find the time taken for her to travel 20km, then from there deduct how long she stayed at the sports complex etc and then draw the graph :)

  The point where all bisectors meet (should meet) is point M. [1]

  Total 4 marks

   

  i drew 2 bisectors >> BC and AB

  i think i got the point though. Shouldn't the third line meet at the same point anyway?

   

  If thats wrong, its a -3 marks total for me ><

  sweee lah. but i think of 10 marks kena burn.. si beh sian.. like no mood paper 2 liao.

  eh the sets question if i put empty set instead of 0 = wrong?

  should be correct bah, because there cant even be whatever intersect whatever. so anyone confirm this?

  i just remembered n = number ):

  so it means number of elements

  i put 2 and empty set

  guess thats minus 2 marks =/

  yes. But cld just do one more extra since i rmb they say A,B, C

  Btw i didnt write calculator model for emath paper 1 i think i die liao.

  Wa.. =/ You better remember to write for paper 2, think they'll check only when your answers are different from the answer key by a bit then they will check against that calculator and see your calculation correct or not or something. So for paper 1, let's hope they don't check luh for your paper.

  hehe yeah. Actually my plan was to write the model after the paper but right in the last sec, I saw a terrible careless mistake which is i think qn 3 where they asked for simple form. The answer i put was xcube / 8 which can be simplified to (x/2)^3. And then, he siad pens down. =.=

  So i was since depressed. In fact thats the only mark i minus that i am aware of. XD

  So lets just do more prelims and practise patterns! go to ahm's forum to see.

  Will i get penalized?

  You guys manage to do the question with this trapezium and rectangle ? The one which ask u to prove the surface area of the figure equals to a given eqn? few of my friends said there is an error with it? manage to do part(ii) though...

  1 mark question doesnt really need working... i don't really do it with 1 mark

  Yup as far as I remember I don't have any questions on that paper, other than the percentage which I just cleared my doubt.

  the formula for trapezium is 1/2 (sum of parallel length) x height.

  i forgot about the 1/2 at first. until last 5 min. ^^
