[sage-support] SAGE TA ?

2007-03-26 Thread Nikos Apostolakis
Hello group, has anybody tried to implement something like "Maple TA" in sage? For example I would like to have students take placement exams with "free form" answers. In case you don't know what Maple TA is: ,[ http://www.maplesoft.com/products/mapleta/ ] | Maple T.A. is an easy-to-use w

By strange coincidence, I am familiar with SAGE, MAPLE TA, and math validation and placement (I'm one of only two at my school who gets some summer pay for doing this)! I think this would be great, but significant work (obviously) to get set up. My recommendation, in case someone wants to do this

[sage-support] is_prime for polynomials over ZZ

2007-03-26 Thread Timothy Clemans
I just want to tell the user of my factoring apps when the quadratic that they submit is prime. I've tried is_prime, and len(factor(x^2+B*x+C)) (thinking an answer of one would mean its prime, but it does not mean that). What is the best way in SAGE right now to test a polynomial over ZZ to tell i
