Been ages since I've been here. At any rate, I need some serious help here. Ok, its from puremaths paper-4, may/june 2009. The questions are attached. And in case you can't get the attchments, well they are questions 5 and 6 from the questions paper. I'm having problems specifically in 5)ii and iii. And in 6)ii, iii and iv.
Okay If I have any more problems I'll write em down. Thank you.
