PuLsE Posted May 7, 2008 Report Share Posted May 7, 2008 (edited) Anyways for (a) (i) the vertical distance p would just be g(x) - f(a) (ii) Since you have the equation for "p", then just take a derivative and test for a maximum p=10x+1-e^2x p'=10-2e^2x 10-2e^2x=0 2e^2x=10 e^2x=5 2x=ln5 x=ln5/2 x is about .805 p'(.5)=+ (increasing) p'(1)=- (decreasing) Maximum at x=.805 Also, I was looking for some specimen papers. Do you know where I can get some? Edited May 7, 2008 by PuLsE Reply Link to post Share on other sites More sharing options...
deissi Posted May 7, 2008 Report Share Posted May 7, 2008 For math, there is only one specimen paper for HL and one for SL. For the new syllabus, you can get P1 and P2 of M08 (TZ1&TZ2) pretty soon though Reply Link to post Share on other sites More sharing options...
