yeeeeeee6 subintervals = 7 function values
And as for the radium one, it was about the ratio (ie after 1600 it was half: Ae^(-k x 0) = 2Ae^(-k x 1600), and the A's cancelled out then you just had to use normal log laws and such to figure out k.
u had to use the slopes they gave u at the points o and PYeah knew they would do this....the roller -coaster one..i didnt know where to START..what were the concepts used ????
so much for it being 2u.!
WTF was up with the decay question about radium? I swear there wasn't even enough information to complete the answer! That test was dodgy...
1921?wow... what can i say.. what the hell is wrong with all of you? that exam was easy.. by far the easiest exam in the past 5 years... i have done every past paper from 1921 onwards and this was easy peasy... Q10 was a joke, finished it in 5 minutes... why did everyone think it was so hard? 115+/120 for sure i love math
Well we're sorry..not everyone does 90 years worth of exam papers.wow... what can i say.. what the hell is wrong with all of you? that exam was easy.. by far the easiest exam in the past 5 years... i have done every past paper from 1921 onwards and this was easy peasy...

me too... im pretty sure that's right, because there was a +1 on the end of the 5/12 - 2ln2I got 17/12 - 2ln2.
