    Determine the norm of an operator Tf(t)

    Im starting to learn the subject so I am looking for resources and books with similar examples.

    Determine the norm of an operator Tf(t)

    Im sorry, I missed the square root. What do you mean by the thing on the left/right? Do you mean the left hand side and the right hand side of the equation? Or do you mean the left and right terms in the integral?

    Determine the norm of an operator Tf(t)

    My understanding is that the norm for T has the form ||T||2 = int (|g (t) f (t)|^2) dt Could you recommend books or resources with similar examples to the problem?

    Determine the norm of an operator Tf(t)

    I am just not able to find a function, which maximazes the operator or a sequence of functions. Can you give me a hint if you know?

    Determine the norm of an operator Tf(t)

    Yes, T is an operator on L^2(0,1). I was able to show it is bounded by ||g|| in L^infinity(0,1). But I don't know how to find the norm.

    Determine the norm of an operator Tf(t)

    I don't know how to start to find the bounded condition nor the norm. I thought about finding a maximal norm to show that it is bounded but I don't know how to continue.

    Sum of a series from n=1 to infinity of n^2/(2+1/n)^n

    Thanks, I am just being ask to find a way to get the number of the sum I also used a calculator to get the result it is 3.77381 but I am being ask to use a method to get to that result.

    Sum of a series from n=1 to infinity of n^2/(2+1/n)^n

    Hi, I was just told to get the sum from n=1 to infinity of n^2/(2+1/n)^n

    Sum of a series from n=1 to infinity of n^2/(2+1/n)^n

    Yes it should converge. There are no similar examples that I know of. I am looking in textbooks to try to find something similar.

    Sum of a series from n=1 to infinity of n^2/(2+1/n)^n

    Thanks a lot, I am asked to find the sum of the series not to show if it converges. How is possible to start with that?

    Sum of a series from n=1 to infinity of n^2/(2+1/n)^n

    I tried to write it as n^2/2^n (1+1/2n)^n But I am stuck there and don't know what to try next.Thanks for any help in advance!
