Specialist Exam 1

[Splash-Tackle-Flail]

How did you guys find it?

Hard? easy?

[bobisnotmyname]

I went really bad

[GeniDoi]

Stupid mistake galore. Bye bye 40.

[Maths Forever]

Could anyone please upload a copy of the exam? Thanks

[bobisnotmyname]

yeah, answers to the exam would be great

[alchemy]

Hopefully full marked it.
Found it to be a pretty easy exam tbh.
Did way better in this than methods LOL

[Deshouka]

For the cosec(2x)<cosec(x)

Is the answer (0,pi/3)?
And if for part a i wrote
Cos(x)=1/2
x=pi/6
Hence (0,pi/6), would I receive conseq. marks?

[Escobar]

For the cosec(2x)<cosec(x)

Is the answer (0,pi/3)?

i got  (0,pi/3)U(pi/2,pi)

I actually did pretty well on this. Probably some mistakes I didn't pick up on, but I'm happy with how I did. I honestly think I did better in this than in methods. I only didn't end up putting down an answer for the very last question. I think my workings will get me 1 mark for it though. Pretty happy overall.

[bobisnotmyname]

just wondering, does 1 mark exam 1 = 1 mark exam 2, or does each exam get taken and scaled individually?

for the velocity question, did we have to explain why we chose our answer? i.e. since v=e, x=1 or something...

[zsteve]

i got  (0,pi/3)U(pi/2,pi)

I got (0, pi/3), but not the other half.

[cosine]

I got (0, pi/3), but not the other half.

SAME WTF?

which one is right?

also if you write 0+0i for the cartesian equation instead of just 0, is that right?

[anonymous 774]

i got the same as escobar, because 1/sinxcosx will always be negative in the second quadrant, whereas 1/sinx will always be positive

[zsteve]

I got (0, pi/3), but not the other half.

By the way, I managed to mess up the arctan integral question, but I fixed it up towards the end (discovered my error during checking). My mistake was I calculated the area I wanted to subtract from the rectangle, and my working was quite messy, and I had to quickly fix up the working to half make sense. If my working is a bit scattered and not in order, but it yields the correct result, what are my chances of retaining the method mark? (It was a 2 mark question, is that right?)
