Right now I am planning my year 3 units for my Acst/Computing double, and start thinking a little ahead about year 4 since most Comp3xx units required certain Comp2xx as prerequisites. Are there any current 3rd and 4th Yr'er here with computing double to share about your subject selection...

hope this is not too late, I have Econ110, Stat171 and Econ111 textbooks to sell, anyone interested drop me a pm.

B Com- Actuarial / B Sci - Computing @ 2nd year, classified as the endangered species

opps, i mean a^2(n) is positive and increasing, and (a^2 )(n) < a(n)^2. Since a(n)^2 is convergent, so (a^2 )(n) is bounded above still no clue for the Calculus 1st question tho: "suppose a(n) --> L as n --> infinity, and b(n) = f(a(n)) where b(n) is continuous, prove that f (a(n) ) --> f...

To prove convergence you basically need to show that it is bounded above and increasing (or bounded below and decreasing), in this case, a(n) is obviously incresing since all An positive, and it is smaller than (bounded above by) (An)^2.

thx wogboy, how abt this one: suppose a(n) --> L as n --> infinity, and b(n) = f(a(n)) where b(n) is continuous, prove that f (a(n) ) --> f (L). any thoughts on that as well?

yes i'm struggling with the following: Calculus: Find the limit of a(n) = n(2^1/n - 1) if exists and "Find sequences a(n) and b(n) such that a(n) has a subsequence converging to 2, b(n) has a subsequence converging to 3, and a(n) + b(n) --> 4" Algebra: "If H is an m x n matrix and K...

i've heard this from a friend before: econ111 = essay/story writing, any thoughts on that?

everyone's happy, leaving me out in the dark.. ACST151 Intro to Actuarial Studies First Half Year CR 69 COMP125 Fund.of Comp.Science First Half Year CR 69 ECON110 Macroeconomic Principles First Half Year D 81 STAT171 Statistical Data Analysis First Half Year CR 69 did i score some...

it must be the student activity fees...

4 am now, site still down...

hey are there any units that we cannot fail? or do we have to pass everything?

Econ110: did alrite in all sections, so think no prob with C, maybe D if lucky Acst151: took some guesses(5) in MC but mostly ok, wrote answers to Q31 but not sure if i'm right, so most likely C Stat171: got all formulas in my cheating paper, so nothin should go wrong, except maybe the 2...

i think you are just looking at the sign of (α. + NLF. – Y) to be either positive, negative or zero, which respectively relates to rising, falling and constant U...am i right? :X

lol, that looks identical to mine.. have my account been hacked by redrum or something?
