Holy shit 4a asked for the range too?

I quit life.

[xenial]

question 4a) also asked for range!
in question 7, y=-1/2x as an asymptote is completely unnecessary due to the range! the graph NEVER approaches y=-1/2x (the definition of an asymptote is for the function to approach it). thus, y=-1/2x should not be shown as an asymptote!

I included it to be safe. No way they would take marks off for that. That would be absurd.

Can someone please put up the worked solutions to the Newtons Cooling Question?

Here's pics, I'll post the whole thing when I'm done

If they take marks off for that...jerks, all of them.

I think I got like 30/40. What do you think the average would be? ):

I honestly feel so stupid for being unable to anti diff for the newton cooling question.
Why could I not remember +c ......
Like seriously 5 marks gone.

Woah, I did it very differently (and not nearly as efficiently) but still got the right answers. :S

Thanks for the solutions! 
Will I lose a mark if I wrote W for the weight force instead of 10g?
I honestly don't know why I didn't include that since it's come up in so many practice exams.

I feel that should be acceptable. Not 100% sure, about 90%.

Okay cool, thanks. That makes me feel 90% better haha.

Did so much better in spesh than methods haha!

for question 8, i had z= + or - root(1 +i root 3) and z= + or - root(1-i root 3)
is that right?

That is right - but you would have to simplify the root.
z=rcis(theta)
z^2=r^2cis(2theta)
Solve from there.

Sorry to hear that, but I think you'll still get two marks!

I did that too. Oops. I knew something was suspicious with the sqrt or a sqrt
