My Suggested Solutions to SP2008 Exam 2 [Confirmed]

[jamestaR`]

Yeh i made exact same mistakes as you synesthetic for 2 and 12, and had no clue for 17 so guessed it and got it wrong.

And extended can get fucked, how are u supposed to do that last area question! I forgot the year 11 segment formula and could think of no other way.

Yeah i thought that it was rat of VCAA to put a Q related to the year 11 syllabus. I took a guess at the formula and before using it, tried it with random circles with random radii to with angle pi to make sure that it was right.

You could have integrated...

Oh yeah that's right. 2 decimal places, and we got our calcs. lol Stupid me

[julz]

well i slept thro my exam and i got 12/22 multiple choice right
so
dw
u guys will beat me
and can people who did shit please post coz ur making me feel liek crap with all these solutions
i didnt fkn do anythign!!!!
it was sooooooo harddddddddddddddddddddd

[jamestaR`]

INtegrated how? you couldnt use the "top minus bottom" method because the circle went went outside the point of intersection.

And i dunno how to use calc to find 'top minus bottom' areas so..

I did shit
i answered 2.5 questions out of 5 in analysis and i did worse than you in multiple
those fucking cartesian equations......

I couldn't get the cartesian equations as well. GRR

With 10 mins to go i think i did find one of them
but i forgot the +-
so when i drew the graph it was half an '8'

Im so fucking dopey lol

will be heaps happy with 40/80 although i dunno if i'll get that
i would take 30 raw atm and run with it.......

[polky]

I did the area of the circle thing this way (picture attached), which didn't require any integration.

Don't know if that's technically correct?  Might have gotten 2.53 as a fluke.

Can someone pleeease explain to me.. how do you do MC 18? the one with the magnitude of F in the direction of d

[Synesthetic]

Can someone pleeease explain to me.. how do you do MC 18? the one with the magnitude of F in the direction of d

That's the scalar product.

F . d hat = [F . d] / magnitude of d

*edit* Answer is E ... as per the post below yours

[csq7]

so whats the correct answer?

[hamtarofreak]

It's just asking you to find the component of F in the direction of d.

Thus, you're looking for

Which is also - answer E

oh right!! thanks!! now why didnt i think of that during the exam!! *slap*
