My Exam 1 answers

[hyperblade01]

Also for Q 3 I just left it as perpendicular component = blah blah and parallel component = blah blah. Do you guys think that's fine?

If it makes you feel better, I also did that

I think it's just me but I can't read latex? it's coming up in code form

[bloodboy]

my bad didnt see the small -

[TrueTears]

Awesome! Looks like everything else is fine to me.

Jimmy you got your end tags the wrong way around should be [/tex] not [\tex]

how could you solve k, there wasnt any boundary conditions

Um can someone explain this to me? I also don't see how you can solve for k ... :/   
That intergral to solve v in terms of x is very depressing -.-"

sub (1,1) into the original equation.

what!?
i don't get how we were meant to find k??
it didn't not say to write the gradient in terms of k.
I just left it as -7-k,
do u guys reckon i'll lose marks for that?? :S

[tomygun_123]

i dont think you could solve for K, in the previous question it asked to solve in terms of k, x and y so you could just leave dy/dx in terms of k... just a thought.

[TonyHem]

You can solve for K
and yeah you will lose a mark
(JOIN ME: HAHAH I didn't solve for K either  )

[dav132]

ah yeh, that makes sense.
but still, it didn't say find k!!

maybe because the question didnt say gradient in terms of k
i did the same as u
what was that out of ? that part

[hyperblade01]

I reckon 2 marks

EDIT: Yea i think it was as the page was 2, 2, 2

[gilla]

my Question 9
a) y = -2 +2tan{(2x + \frac{\pi}{4})}

my tan wasnt simplified, do you think they'd take marks off?

2 mark question I think

[TrueTears]

2 mark question.

I *think* it's 1 mark 1 subbing in the right value of k.

Another mark for the right answer.
