In this task, I am analyzing partial sums of power series. At one place, I call exp = collect(expand(exp), m, factor) The expression exp is a partial sum of a power series in powers of m. After this call, I have one more manipulation and then I print the results. For the printout, I would like to see the power series in ascending powers of m 1-2m/3+7m**2/18 but collect returns descending powers 7m**2/18-2m/3+1 I was hoping I could call collect and pass a parameter for the order of the output, but didn't find anything. Does anyone have a recommendation?
