Hallo, I was wondering if anyone had any pointers about writing/ reading complex mathematical expressions such as these, [(34 - 30I)*exp(1.5 - 6*i)(theta)] + [(25 - 35*I)*exp(2+3*I)(theta)] into/from a text file. I need to copy such data from one maple worksheet into another. I appreciate any advice in this matter. Regards, Virat
