Homework Statement



Let V be the linear space of all real functions Differentiable on (0,1). If f is in V define g=T(f) to mean that g(t)=tf'(t) for all t in (0,1). Prove that every real λ is an eigenvalue for T, and determine the eigenfunctions corresponding to λ.

Homework Equations


The Attempt at a Solution



All I know is that f'=λf and T(f)=λf in general. I tried substituting the variables, and I ended up with only t, which doesn't make sense.

Can you use the definitions of "eigenvalue", "eigenfunction" and T to explain what "f is an eigenfunction of T with eigenvalue λ" means?

Edit: You have already given a partial answer for that by saying that Tf=λf. This is the part that follows from the definitions of eigenvalue and eigenfunction. So now you need to use the definition of T to explain what Tf=λf means.

There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
