This was definately the hardest 3 unit exam I've done, although I found 7 slightly easier than 6 - in that the algebra was so hard in 6! Compared to last year's paper this was uber uber hard. Questions 1-5 (excluding the induction, which I didn't manage to get, although I have now...) were fine...

Hi everyone - try this one, "What is the volume generated when the are under y=e^((-x)^2) [e to the (minus x squared)] between x=0 and x=1 is rotated about the y axis?

Ya - every time you get something with sinx and cosx in the same equation, use the AAM to get the equation into just one trig function, then solve it like any other trig thing with base angles etc. They will usually ask you to "express in the form Rsin(x+a) or something similar. That's the...
