Trying to calculate the determinant of matrix A i have to add extra details to the function (integer) to get result (for example): Det(A) - does not work for me, but - Det(A) mod 10000 (or 10^n); - does and gives the result (honestly it took me a while to get it clear, i mean to get Det(A) work). I think it's not the way it is supposed to work. In help it's simply clarified that Det(A) function should give the result of determinant of matrix A, without any additional integers like mod :/. I can't figure out this riddle.. (i've started using maple 3weeks ago, and mostly for algebra and geometry). Any help pls? Do i have to change any settings? Tnx, in advance =).
