When inverting some z-transforms, Maple V.1 gives me terms of the form
(a+I*b)^n, (with floats a and b), but it is important to me to have them
in the form r^n * cos(n*w) and r^n * sin(n*w) instead (especially since
the result should be real, but has a very small imaginary part due to
'evalf's'). How can I coerce Maple to give me my preferred form? I've
tried simplify(*,'trig'), but it doesn't do what I want, even with n
declared integer.
