Hancock's 2nd Practise Methods Exam 1

[Hancock]

Hey again,

I've created another Exam 1 which you guys could try if you like. In my opinion, it's a tad harder than the last one, so we'll see how everyone goes. I hope everyone did well on English.

[malekv]

YAY! Thank you Hancock! I'll try this tomorow morning

[Lasercookie]

Awesome, Hancock. I'll have a go at it soon, maybe later tonight if I'm bored.

Also chucking the link into the resources thread with your other one.

[Hancock]

Thanks everyone, I hope it's helping you all prepare for Methods on Wednesday

BTW: Mediafire is apparently down at the moment, but it should be up soon. If not, I'll chuck them on a different filesharing site.

Hancock, how did you do question 2a) without calculator?

Hancock, how did you do question 2a) without calculator?

you use u substitution.. make u= 3x^2, find du/dx = 6x
therefore, dx=du/6x
and solve from there

btw, very good exam, liked it
probably one of the best exam 1's ive seen going round
perfect vcaa style 

[Hancock]

Awesome, cheers buddy. I'm glad you liked it.

Exam 1's are kind of easy to make, because after you've done heaps you know what questions they will ask. Exam 2 on the other hand...

Nice exam mate, really well written

However, on first inspection I don't think 2a is really a methods question. I'll admit it could certainly be done intuitively by some, but I don't think it's on the study design.

[Hancock]

Hmmm, I suppose not, more a spesh one. However, since I can sort of be done with Methods techniques, I don't think it's a massive reach. Sort of like how they used the constant of proportionality in the Exam 2 last year. All my non-spesh friends were like WTF.

Thanks for the advice though

[diligent18]

I ACCEPT THIS CHALLENGE.
Thank for writing this up!

for #6 b)
how do you get radius =[value given in answers] when Volume of sphere = ?
or is this just me?

for #7 c)
in the answers, you keep referring to and not
not sure if the final answer is correct, but the working out is definitely not.


but overall awesome work. I found it certainly a bit tougher than your first exam

[Hancock]

Ah shizzle, the volume was meant to be 32pi/3 which would make it r =  that value. I'm fixing it now.

However, with the answers, I just fixed it to say 7pi/4. It was originally 3pi/2 and I didn't change it when I changed the questions. The answer for 7c is correct however. Thanks for letting me know, I'm updating the files now.

[Hancock]

Ok guys, I just fixed some errors and uploaded the corrected files. So if you've downloaded them before, give these knew ones a download before you start.

Cheers

no worries.
I just got so worried because I saw the answers and just didn't understand what was going on there haha
