ACCT2012 doesn't build on ACCT2011. 2011 is all financial reporting and the like, you have to remember/know heaps of bs accounting standards. Pretty boring in my opinion.
Yea, the second range is 19.67<x<20 because the range is a maximum at x=1, not 19.51<x<19.67, so the width isn't 0.159.
Btw, are there two solutions for each x and y in 5(c)??
if u let x=30 degrees, N=reaction , F=friction and resolve forces horizontally and vertically, you end up with
Equation 1: Nsinx + Fcosx= (mv^2)/r
Equation 2: Ncosx - Fsinx = mg
(Equation 1 times sinx) + (Equation 2 times cosx)= N
(Equation 1 times cosx) - (Equation 2 times sinx) = F

Yea, I mainly said he shaped events as he stayed true to his ideology despite his being arrested, exiled, 1905 failure etc. But then in the power struggle, he let events such as Stalin's maneauvres shape him to an extent. Dunno if that's right.
