I am working on that. See http://sagenb.com/triBC I plan to implement an interactive algebra textbook. My question is say you were teaching factoring trinomials of the BC form. How would you have your students practice on the computer? On 3/31/07, Jurgis Pralgauskis <[EMAIL PROTECTED]> wrote: >

Hi, I've been trying to work with quaternion algebras in SAGE, but with rather mixed results. I'm not sure whether this is due to incomplete implementation or just to the fact that I'm doing things the wrong way. Anyway, here are some examples: I define the quaternion algebra H over the ration
