Pick Peter Andersen as the tutor and fins1613's gonna be easy and interesting, 100% for all the quizzes so far =).
I've stopped going to fins1613 lectures after Rob's gone, apparently Zhian took over and all of my friends said they can't understand him....
Not sure if you've received my pm or not :S laptop blacked out after I clicked submit...Sorry for the late reply and if you didn't receive it please tell me
u^n / 1+u^2 < u^n
integrate both sides from 0~1
LHS becomes In, which is less than [1/n+1 u^(n+1) ](bounds from 0~1) = 1/n+1
hence In < 1/n+1
since In is above the x axis except at u=0, then the area represented by In is positive In>0
thus 0 < In < 1/n+1
hence 0 < I2n < 1/2n+1
limit as...
