Re: [sage-support] Problem installing on Ubuntu 18.04

I  do the following: - cd ~/bin - untar the Ubuntu 16.04 version - rename the ~/bin/SageMath to ~/bin/SageMath-8.3 so that I can have multiple versions if needed. - ln -s ~/bin/SageMath-8.3/sage sage-8.3 - ln -s ~/bin/SageMath-8.3/sage sage # My default version ~/bin is in my path, so I can j

I'm trying to figure out how to orient a 3D plot. I found a keyword 'orientation' that takes 4 parameters, but I don't know that they are. Can anyone explain them? Thanks, Andy -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe f

[sage-support] latex rendering problems

I have two problems rendering latex. The first is in a plot title. The fraction should be centered. If I try the same latex: \sum_{n=1}^{\infty}\frac{12}{(-5)^n} at http://www.codecogs.com/latex/eqneditor.php it renders as I expect. The second problem is rendering latex for a table. I thought

Re: [sage-support] How do I use @interact with sage 8.0 jupyter notebook?

Henri, I was running 8.0 from the tar file on sagemath downloads. Thinking that I may have messed up the notebook with previous commands, I restarted sage -n and tried the https://wiki.sagemath.org/interact/calculus#Some_polar_parametric_curves

I'm trying to learn how to use the @interact command. The examples here: http://doc.sagemath.org/html/en/prep/Quickstarts/Interact.html do not work. I get a stack traces complaining about variable types etc. Other examples I tried: https://wiki.sagemath.org/interact/calculus#Some_polar_paramet

[sage-support] Title and tick formater ignored with graphics_array

I'm trying to make graphics array with plots containing tick marks and a titles. When displayed individually, a.show(), b.show(), they display correctly. In a graphics_array however, the first graph looses these attributes (b). f=4*sin(3*x) b=plot(f,0,pi/3,ticks=pi/6,tick_formatter=pi, title="
