Well, I thought I'd try one of these cloud severs for a change. cocalc.com has the latest version the latest version of SAGE, I just assumed it had the latest version of Python too. Silly me!
That's why i need to input a=float(0) for the first Riemann Sum. It didn't click. Sorry, I've been teaching Java all year. This is the first time I used Python this year which is unusual for me. So, instead of a=float(0), could I just write a=0.0 as a=0 brings up this issue? In fact, is it sufficient to write all integer constants as floats like 7.0 instead of 7? Or should I just "import from _future_ division" and be done? Thanx, everyone for your help!!! TIA, AJG Sincerely, A.
