Q19)a) a= √a b2=a2(1-e2) i.e. e2=a2-b2/a2 e=√a√a2-b2/a Foci(±√a√a2-b2/a,0) Directrices: x= ± a√a2-b2/a2-b2 Now, SP/PM=e, S'P/PM'=e (Ellipse Property) i.e. ePM=SP, ePM'=S'P and SP'+S'P = e(PM+PM')=2a=2√a using e(PM+PM')=[√a√a2-b2/a] *[2a√a2-b2/a2-b2] = 2√a =2a (as required) b)...

for v) i get: y=x1/x taking log of both sides: lny=lnx1/x=lnx/x diff. both sides implicity: y'/y=1/x2-lnx/x2 = 1-lnx/x2 y'=x1/x(1-lnx)/x2 edit: got it now, made a careless when differentiating.

hmm, yeah, but i thought comm. systems were a part of a Information System. I havent seen the project plan section included for the Comm. Sys section in most text books. But anyway you could apply the feasibility study, and conversion methods in the project plan for a comm. system. An you can...

Yeh, its sort of a reverse chain rule: ∫[f'(x) . f(x)^n] dx = f(x)^n+1/n+1 + C

hmm, how long do you guys spend on 4U topics usually. We got a calendar program which indicates when we're doing particular 3U and 4U topics.

kewl, are u a misticriver, member btw?..irivers pwn, i have a h320 with an open source firmware called RockBox, check the link it has way more features than the stock fw, and still going. Only downside to the H3xx irivers is the size compared to the ipods, but the features and options outweight...
