[sage-support] In terms of graphing, how to associate x with each member of a sequence?

Hello, all. It's my first time posting here, cause I have only first learned sage this semester and am using it in a math modeling class and I really love it. This is my first question I cannot figure out myself by searching online, though I'm sure it's an amateur question, so bear with me. I

[sage-support] Finding the roots of a polynomial

I need to find the roots of this polynomial, where are coefficients are in this matrix: coef=matrix([[1],[-1],[-1],[0]]) thanks in advance, and apologies if this is posted somewhere else, I have not been able to find it. (NOTE: looking for the MathCAD equivalent of "polyroots") --~--~---

[sage-support] Ugly Maple output in notebook

The maple output in the notebook is ugly since the linebreaks don't line up. For example expand((a+b)^20); produces a^20+20*b*a^19+190*b^2*a^18+1140*b^3*a^17+4845*b^4*a^16+15504*b^5*a^15+3\ 8760*b ^6*a^14+77520*b^7*a^13+125970*b^8*a^12+167960*b^9*a^11+184756*b^10*a^10+ \ 167960 *b^11*a^9+12597

[sage-support] notebook password

. But I did not ever set a password and without an old password it does not want to let me set a new one. Can I tell Sage which browser it should use? How can I assign a password? I use Sage on a Mac and am the only person using the Mac. TIA Bob Wonderly --~--~-~--~~---

[sage-support] long arithmetic

Using Sage I solved a long list of equations and put the solutions (s) in a list; e.g.: sage: for j in range(52,54,1): q = slst[j] j=q[0]; k=(q[1]); s=(q[2]) (q,j,k,s) : ([52, 30, 2081203288L], 52, 30, 2081203288L) ([53, 53, 17903198518682712L], 53, 53, 17903198518682712L) No
