Debrief -> E Mathematics Paper 1

Neutral My angle bisector wasn't drawn properly Sad I hit the staple on the paper, and my line is inaccurate Crying or Very sad

As for the speed-time graph, I drew Straight for both 0-10 and 10-20 Neutral But my sister told me should have drawn curve at the start Confused

eagle SG

Just go. It can't get any worse than B3. Any better is a bonus.

Darkness_hacker99 SG

Ok~ I'll go tomorrow~ Smile

lpx88 SG

Why curve?They say constant acceleration leh Confused

TrixCereals SG

From the distance time graph you go calculate the speed for each point den plot. You see got straight line anot. Laughing

lpx88 SG

Ya thats wad my friend did. But still the question itself said that the accelration was constant in the beginning Confused

absol SG

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...

Darkness_hacker99 SG

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%

absol SG

i wanted to write 70%, den decided to write 80%, then decided it was too much and cancelled and changed to 75% lol

lpx88 SG

i wrote 75

Fireindahouse SG

waaa that one very weird..!!

absol SG

eh. so any1 got curve in the locus?

Fireindahouse SG

me! part a3

lpx88 SG

I use the series of mini curves to draw the actual straight loci. Counted ornot

Darkness_hacker99 SG

Yar. Should have.

4cm locus.

Fireindahouse SG

ur line is all the way straight = no.

Darkness_hacker99 SG

Correct! Wink

But the straight line must touch the curve for it to be counted. Smile

When my teacher taught me this chapter last year, he said it's floating clouds Laughing

icyboiz SG

not to mention i forget to bring my mathematical set, im doom

lpx88 SG

Why not?How must it look like?
