Yep it was multiple choice. I might have been tricked.. i'm not sure.. :( Now i'm worried Also, did anyone notice that question about selecting the different graphs for changing electric field strength, acceleration and velocity in the MC? I think that question is incorrect..

It was question that fooled a lot of people. One of those tricky ones. I'm not too sure if i got it right. To try jog your memory, it's the one about graphing the net force on a metal sheet free-falling in a magnetic field. I think the Q2Q questions were quite straightforward as well. Put...

lol i remember seeing that question, i hope i did it right though now that i think back :( What do you think of the question that needed you to draw a graph?

Thoughts? I found it quite straightforward, nothing too tricky in it.

Haha not really, i don't really freak out at things.. lol I said that because i felt like i did horribly for the majority of my exams :/

This looks nice: http://www3.ul.ie/~mlc/support/Loughborough%20website/chap15/15_1.pdf

It's natural to freak out for your trials which have such a large weighting. However, the more prepared you are, the less you will be freaking out/stressing. If you get in to a consistent study routine now, you won't regret it down the track! :)

Did not do good... expecting to drop ranks for all my subjects.. except physics.

Really depends on how complex the area we need to find is. mm i don't time myself lol.. but work at your own pace, you'll naturally get faster with practice.

Sketching makes things so much easier. I generally sketch a quick graph every time i'm finding area/volume.

Should have picked two from economics/biology/modern history for year 11. Most definitely would have carried one over to year 12 for 12 units.

When you're trying to find the area between -1 to 0, it uses the y-values of the graph. The y-values between -1 to 0 are negative, so you end up with a negative value for the area.

Yep

Bingo! Semicircle of radius 1. Try graph it

Remember what integration helps you find. *cough* area *cough*

Calorimetry: Calorimetry is the science of measuring the heat of chemical reactions or physical change (from Wiki) E.g. determining the heat of combustion of ethanol by heating water.

Re: MX2 Integration Marathon I don't know how to explain it otherwise, but if you use the substitution u = 2x, you get that next line.

As x-> 1+, f(x) -> -infinity, e^[f(x)] -> 0+ As x-> +infinity, f(x) -> 0-, e^[f(x)] -> 1- As x-> 1-, f(x) -> +infinity, e^[f(x)] -> +infinity At f(x) = 2, e^[f(x)] = e^2 etc. Basically break it up and use what you know about exponentials to get the general shape of the graph and sketch.

From the paper

It is technically finding the square roots. x = \sqrt{-16 + 30i} x^2 = -16 + 30i Good luck and have fun with 4U :)
