Is there a way to find out the rate of decay of function f(x) when x-> +infinity? Hi all, I just wanted to use this real-world engineering problem to practice problem-solving using Maple. Suppose I have a function f(x) (probably complex valued), how to find out its rate of decay as x approaches +infinity? I used "limit" but it will give me a value, not a functional form. I already knew my function has a limit =0 at x=+infinity. And it is of fast decay. I would like to bound the limiting behavior of f(x) by exp(-alpha*x) for some suitable constant alpha. Is there a way to handle this in Maple? Thanks a lot
