comment If $a_1a_2\cdots a_n=1$, then the sum $\sum_k a_k\prod_{j\le k} (1+a_j)^{-1}$ is bounded below by $1-2^{-n}$
Could you let me know the name of that formula pls.

Well... the last case has imaginary roots. (I added solution in the back of the book to the question).

comment Determine the eigenvalues (and corresponding eigenfunctions) if phi satisfies…
Well, I know that for only certain values of lambda I have non-trivial solutions; the formula in the book is: lambda=(n*pi/L)^2...This has to somehow be part of the solution. PS: My book is very poor at explaining and has absolutely no examples so I am stuck at square 1.

comment Determine equilibrium temperature distribution.
Great! However the way I am learning it from the book is different, and I am not sure how "The first boundary condition implies A=B−T..."

Yes, external source.

I will attempt using your suggestions. Btw the back of book answer is: u = T + a(x + 1).

comment Determine equilibrium temperature distribution.
Yeah, I misunderstood it seems, usually I try to get u(0) and u(L), but from these partials how do I get it?
