i think so.. there was something on the first page with like, find the value of K for which ___ has equal roots. then i used b^2-4ac = 0.
i think i got k = -2.. but i cant be sure if that was the question. i dont have the best memory.
aaastars:
oh yea... there was sth like that, the first few qn. thxs

erm..no...LOL...i dnt remember..
but, i hope relative velocty wont come out..cuz i didnt learn tht.my teachr didnt wnt to teach us tht topic..so i just hope tht it wont come out.
..but just in case. i'm trying to teach myself. so any1 has notes on relative velocity?
aaastars:
i think its very likely to come out...
well you better get a grasp of it, at least. it can be very easy and sometimes very tedious.
