    There are a few ways of finding the maximum and minimum values of a function in Maple. This is one of the ways I know how to do it.

    defining the function

    >f:=x→ln(x)/x;

    Plotting the function

    >plot(f(x), x=1..10);

    differentiating the function

    >df:=diff(f(x),x);

    finding the maximum or minimum relates to where df = 0

    >xmax := evalf(solve(df=0,x));

    Determine the maximum

    >evalf(f(xmax));

    Hope this helps you. Thanks
