it is still valid if a or b = 0 therefore line 2 of your working out is incorrect
|x +b| or |x+a| can be = 0 therefore line 1 of your working out is incorrect
if i were you (i.e a more creative person) then i would choose chemistry (has almost no maths excepft for a few calculations) ext1 english (its just a few extra essays and texts) and also history (it suits people who are into literature) but thats just imo
From what I've heard school rank is pretty important unless you're consistently coming first. For example, say if your coming 3rd (internal rank) and you come 2nd in your externals with 90% and another guy got 89% (coming third externally). your overall will be half of your own external mark +...
i was in your position during the end of year 11 deciding whether or not to drop 3u. even my parents told me to drop. but for some strange reason i stayed and worked really hard an now im in the top 3 so I reckon you should at least try ext1 until first term of yr 12 then based on your topic...
yea thats what you do in these types of questions. on working out paper u make em meet in the middle and on the test paper you play with one side to meet the other (i.e. working backwards from your working out)

school rank infinity
first English test put me in the top 3 second English test i got eaten
tbh hsc year hasn't been as fruitful as expected
btw nice ranks elliottjohnson
holy what ? my comp was down for a whole 3 days how could i have posted? wtf and no i do not currently attend NSBHS and those ranks describe a true genius man. I admire the hackers for cracking my password >:(
btw upgraded to windows 7 woot :p
(e^x+1)/(e^x/2+e^-x/2) = (e^x+1)/(root e^x + 1/root e^x) = (e^x+1)/((e^x+1)/root e^x) = (root e^x)(e^x+1)/(e^x+1) = root e^x = e^x/2
integrate that = 2e^x/2 + C
now teach me how to use equation editor
