Let of ∑an when n goes 1 to infinity and ∑bn when n goes from 1 to infinity be convergent series with positive terms. Which of these series MUST converge? ∑(an + bn)? ∑(anbn)? ∑(an / bn)? or all of them?

This is an assignment I got. I don't understand it at all. What questions should I ask my professor to clarify in order to sound intelligent when asking? Thanks...

1. Using deductive logic, explain how the following correct answers link to the corresponding correct concept or phrase:
NOTE: Inside parenthetical is not the primary answer but secondary which qualified as correct.

A: 1, 8, 6, 2, 12, 3, 10, 11, 5, 9, 4(7), 7(4)

C: 11, 9(3), 4, 12, 1, 6, 2, 10, 8, 7, 3(9), 5

E: 8, 2, 11, 10, 3, 12, 5, 4, 9, 7, 6, 1

2. As in previous exercises, present your defense using the following deductive-logic format:
Mathematics - Objective
a. Objectivity is analysis based on hard, observable facts.
b. Mathematics is the science studying the exact relationships between quantities and magnitudes.
c. Therefore, Mathematics is an objective pursuit.

I'm stuck on these two problems.

Someone showed me how to do one of these the other day when I asked, and I thought I would be able to do the rest after getting an answer, but I don't see what to do when the initial conditons don't have a zero in the parentheses.

btw - the answers the book gives are:

for the first one:

Eigenvalue λ[subscript 0]=0 with eigenfunction y(x)[subscript 0]≡1, and positive eigenvalues {n^2/4} for n = 1,2,3 ...

The nth eigenfunction y[subscript n](x) is sin(nx/2) if n is odd, cos(nx/2) if n is even.

for the second one:

Only positive eigenvalues {n^2π^2/64} for n = 1,2,3...

The nth eigenfunction y[subscript n](x) is cos(nπx/8)+sin(nπx/8) if n is odd, cos(nπx/8)-sin(nπx/8) if n is even.

Any help would be greatly appreciated.
