Hi, i'm studying Green Functions.

I need to obtain the positive eigenvalues of a function, at this time just for first six values, m=1..6

Can i do this in mathcad Prime 3.1??

there's a attached file.

Thanks in advance.

The symbolic solve is not helpful in this case. Better use a numeric solve block or the root-function.

Maybe the attached file helps.

    thank you very much!

    I still have a question. I modified your file, and it still appear its correct to me. I modified just to get de positive values of beta, starting the first positive value in beta_1.

    Is this version still right?

    thanks!

    Sorry, unfortunatly I can't read P3.1 files, just P3.0 ones. PTC had decides that even subversions should not backward compatible.
