Wronskian Determinants help

    1. The problem statement, all variables and given/known data

    Hi, could someone please confirm my results. I just put my answers because the procedure is so long. let me know if you get the same results.

    1) Wronskian(e^x, e^-x, sinh(x)) = 0

    2) Wronskian(cos(ln(x)), sin(ln(x)) = 1/x * [cos^2(ln(x)) + sin^2(ln(x))] = 1/x

    thanks in advance:smile:

    The one is super easy. sinh(x) is a linear combination of e^x and e^(-x). So 0. You don't even have to compute anything. And you are right on the second one as well.
