Samuel, I am the personification of preoccupations upon preoccupations. No problem. My meager attempt lead me to pynac as well, though not into the library itself. I do know C++, so maybe I can make some progress there. I cloned pynac. There are some dependencies to work out to get it to build.

[sage-devel] Developer guide for casual user

2018-09-21 Thread Andy Howell
I'm a casual user of sage and python. I know a little of both, but far far from expert. There have been a number of very minor bugs that I could fix, but was stymied because I don't know, or have forgotten, how to debug sage code, how to find the code be called etc. To the regular sage developer th

[sage-devel] latex for desolve results

2018-09-02 Thread Andy Howell
Hello, I'm not sure if this is a bug or not. I'm just starting to learn differential equations. The latex returned for 'h' below has superfluous () around the '-x' exponent. y = var('y') Plot1=plot_slope_field(2-y,(x,0,3),(y,0,20)) y = function('y')(x) # declare y to be a function of x h = desol

Harald, I think you may have something else wrong with your system. I too upgraded from 17.04 to 17.10. I built 8.2beta 3 with no problems. I'm compiling beta 5 right now. I had problems under 17.04. I think I was missing the fortran compiler. After installing that, it built fine. Andy On 02/

[sage-devel] color for plot3d axes

2018-01-23 Thread Andy Howell
I talked about doing some development on sage a while back. There is a lot that needs doing, but I wanted some _very_ small to start off with. I was trying to plot a 3d object and was not sure which axes were which in the plot. I found plot3d axes, but that only takes one color. I modified it to t

I've been using Sage on and off for a number of years, and am currently using it while re-learning the calculus I took 35+ years ago. I'm definitely the oldest in my class this time around! I'm running the current dev version under Ubuntu 17.04. I have to move to another laptop temporarily. The
