Debrief -> E Mathematics Paper 1
-
Ya thats wad my friend did. But still the question itself said that the accelration was constant in the beginningOriginally posted by TrixCereals:From the distance time graph you go calculate the speed for each point den plot. You see got straight line anot.

quote indigoblues
"AND STUPID LOCUS, THE 4cm THINGY AT THE END HAVE A CURVE, CAUSE THE LINE ISNT PERPENDICULAR TO THE ONE BELOW."
shit today the locus got curve 1 meh?
mine all straight line inside the quadilateral eh...
and...the v/t graph...first part 0-10 sec is a uniform speed increase ie diagonal line(cuz the distance graph is a curve..) from 0m/s at 0s to 20m/s at 10s den after that its a straight line... -
There's one question asking us to find the shadded area of that figure. Weird figure. Any mathematical formula to approach that question? Or it's just pure guessing?
I wrote 70% -
i wanted to write 70%, den decided to write 80%, then decided it was too much and cancelled and changed to 75% lol

waaa that one very weird..!!Originally posted by Darkness_hacker99:There's one question asking us to find the shadded area of that figure. Weird figure. Any mathematical formula to approach that question? Or it's just pure guessing?

eh. so any1 got curve in the locus?

me! part a3Originally posted by absol:eh. so any1 got curve in the locus? -
I use the series of mini curves to draw the actual straight loci. Counted ornot
-
Yar. Should have.Originally posted by absol:eh. so any1 got curve in the locus?
4cm locus. -
ur line is all the way straight = no.Originally posted by lpx88:I use the series of mini curves to draw the actual straight loci. Counted ornot -
Correct!Originally posted by lpx88:I use the series of mini curves to draw the actual straight loci. Counted ornot
But the straight line must touch the curve for it to be counted.
When my teacher taught me this chapter last year, he said it's floating clouds -
not to mention i forget to bring my mathematical set, im doom

Why not?How must it look like?Originally posted by Fireindahouse:ur line is all the way straight = no. -

I lent one of my friend my protractor because she can't find hers. But in the end, this paper doesn't require protractor. -

I wrote 69%.
I go take the length, versus the full length, mutiply 100%. haha.
sians finish early but still a few careless mistakes. -
Now its a competition of who's got less careless mistakes instead.

it always has beenOriginally posted by TrixCereals:Now its a competition of who's got less careless mistakes instead. -
wa shit i kenna scam..nv realise i need to draw curve at the end of the 4cm loci...1 mark right? and it dosent affect the range of readings of x?
my x i got abt... 78 -
At least if paper hard can seperate the A's from the B's.Originally posted by eagle:it always has been
Now if you smart but careless = gg. -

If you know you are damn good for that subject, pray for an extremely hard paper
If you know you are damn lousy for that subject, pray for an extremely easy paper -
It's a straight line.Originally posted by TrixCereals:From the distance time graph you go calculate the speed for each point den plot. You see got straight line anot. -
Really?Originally posted by LatecomerX:It's a straight line.
