i dont think it asked for that
btw were we asked to draw up a slope field table? or just draw it in?
cos i didnt write 2.5,2,1 etc..


I think it would be unreasonable to ask for working out when they dont give any room for it

OMG in my sentence answer, i didn't state the direction of acceleration (but got a=-8/3).. they arent gonna take a mark off for that are they


I dont think they should because the diagram showed the direction of motion, so IMO it isnt necessary to state it (i didnt write the direction, so i'm hoping im right  :) )

I have found where I went wrong on question 10.
1. I can't simplify (2/4sqrt 2 I am assuming I wrote)
2. I can't square my unsimplified answer 4 sqrt 2 properly either (I am thinking that turned into 64.)
Hopefully they will have pity on me and I will get 2/3 not 1/3, because I am thinking I found tan x properly, just in an unsimplified form. I sure bloody hope so anyway.

So annoyed at myself. Last year I wrote d(6x^3)/dx=12x^2 and I wanted so badly to not repeat something similar, this was near the end of a question but so if I am lucky I will get 2/3 for method. Sure hope so...

so 37/38 plus I am not at all confident on the slope field. wooo.

Oh and my internet keeps going on and off, really want to kick it. None of the random neighbour's wireless signals I can pick up it won't let me connect to either. ISP said it was their bad, stupid twits.

Edit: I think I drew the slope field stuff right then ^_^
Edit: I forgot about the dilation of tan on the slope field xD so 36/37 =[

I left question one out of cis (polar) form >_<.

Damn me.

Other then that, forgot the domain & range of the graph, but part c should be considered a consequential error because of that, shouldn't it?

Yep. My guess is cartesian equation gives you the 2 marks. And the domain + range is handled in the graph. It'd be ridiculous to lose double time simply because you made one error. Though it could happen :)

Well that gives me 37-38 / 40. Pretty damn happy with that.

Don't ask me how to get to it by clicking links (I've only managed that once, from looking about 10 times), it works when you change the years thank god theyre consistent with naming

I have a copy of worked solutions on paper which I can scan, but the first post of this thread already has the correct solutions.

I won't post them unless people have any specific requests for working. Sorry to asa.hoshi for typing out the soft-copy of the paper for me. I will not do maths solutions anymore, because typesetting is a pain in the ass on the computer.

I promise I will do it for Chemistry though, and possibly Physics.
