My only math problem is Paper 2 section A speed time graph...not good on that...

why ya?
just remember physics.
if you take area under a speed-time graph, you get distance travelled.
if you take gradient of a distance-time graph, you get speed.

speed=distance/time
distance = speed x time
play ardount with the formula =)

about the MARA thing,y is it so popular now?

log2(4) + [log2 (p-6)^2]/log2(4) = log 2 (p)
4+log2 (p-6)^2=2log2(p)
2^4*(p-6)^2=p^2
16(p^2-12p+36)=p^2
15p^2-192p+576=0

p=8 @ 4.8

if p=4.8

2log 4 (p-6)
=2log4(-1.2)

log4(-1.2) is infinity. that why p=4.8 is not acceptable.

my math problem is paper 2 section B Earth as a sphere

Thanks for clarifying that up

dont worry bout the chapter earth as a sphere.. if u think u aint good at it,simple!.. dont choose that question..
its in section b where u are only asked to do 4/5 questions..

For me depend on questions,i plan to do all 5 questions if able lah..always draw the sphere then list all the coordinate then only start to do..buy watch so no need to at the hall clock..it waste a lot of time....

yeah.. time will be the greatest enemy when in the exam hall..
scarryy~~

There should be enough time to complete your paper for SPM.
I managed to leave at least 20 minutes early for 90% of the papers (with the exception of Paper 1's).
On the other hand..., 3 hours is already not enough for me in Pre-U. Lost 18 marks in 2 questions. Had to skip it due to lack of time.

i got a problem in drawing like, plans & elevation for things like cylinder from the side view =/

Cylinders will look like rectangles from most point of views (with the exception of the hemisphere). Cones will look like triangles from a side view, circles when viewed from the top.
I forgot the technique to draw the plan when viewed from one of the corners though... =P

how does the hemisphere look like from side view ya ?

Half circle loh..

hmm what other shapes can they put at the side ah..

Spheres, cones, cylinders, prisms, cuboids, pyramids.
Basically a combination of the above. There may be some hollowed-parts too (e.g. a cuboid with a hole in the middle, draw dotted lines to indicate this).

heh okie let me go practice =) thanks nick!

after few hour of research i finally figure out how to solve it thank guys

You better master this..It's free point..
In math i wont choose earth as sphere..I confuse when teacher teach...

wakau vick form 4 oeldi so worried
enjoy ur life la study so hard for what leh =_=
just spm meh
i know im giving bad example
XD
