Specialist Mathematics Examination 2 discussion

Quite happy with this exam,
Much easier than the methods exam.
Did anyone get root 3 over 3 for the last page?

Yeah top students in my cohort got root 3 over 3.. so you are likely right

[availn]

Whelp,
I factorized z⁴ + 16 = 0 as (z² + 4)(z² - 4)
I decided to flip d²N/dt²
And I calculated |b| to be root 7

15 minutes gone fixing those mistakes, but still made more after that which I didn't catch. Damn.

Do you think ill lose a mark if I left it as 1/root3?? :sss

LOVED TODAY'S EXAM, got my revenge for all the the marks I lost on tech free for not being awake during that exam, hopefully the state found today harder than usual. Fully confident in my ER answers, nailed the double derivative question (I think) so hopefully 58/58 if I didnt make some stupid mistakes, all my answers made sense though.

But Im not confident about MC, everyone's saying they were nice I thought they were eh, what did you guys get for that arctan(bx) question? D? please be D... Anyway yeah I can see myself losing 2-4 from MC they took me way longer than usual.

Lol I did the same thing for dN/dT... There goes 3 marks

Yup. Same. Tried something similar for the show that question at the start. 5 marks gone.

[hazmas]

any solutions up yet?

[Jeggz]

Oh god - I actually thought I did okay, until I read this thread

I got D by subbing in values haha! What did you guys get for question 4? The one with the z^3 and second quadrant thing...

The arg principle? I had, the union with the negative values, D

omg i did the same thing, left it as 1/root3

Same I think it was E I'm pretty sure thats right

[Vkzem]

I think this should be okay. For example they gave the coefficient of friction for the previous question wit root3 in the denominator.

[jeff.]

Same for the Arg question.

For the people that put 1/sqrt3, surely that's still considered correct?

I hope so!!!

This is true! Thank for keeping the hopes up!!
