2015-07-06 09:41:20 -0500 | asked a question | Sagetex on Windows: Using miktex and sage on virtualbox. How to make it work? Hello! I've installed sagetex (2009-06-26) using the miktex package manager. I use Sage 6.7 on Oracle's Virtual Box, as recommended for windows users. For me, the following code:
Gives this output:
All the sage commands just give "??" in the latex document. I've been looking at the documentation, but it doesn't seem to be for windows. Is sagetex supposed to work out of the box, just installing it on miktex and having sage installed on virtualbox? If not, is there an official procedure to make it work? e.g. documentation about sagetex on windows?
Thanks! |

2013-11-03 02:13:24 -0500 | asked a question | Plotting the effects of a linear transformation on a grid I am a student taking a first undergraduate course in linear algebra, and I would like to play around with plots of transformations of the type $T:\mathbb{R}^2\rightarrow\mathbb{R}^2$. I already know a bit of python, so I'm not looking for anyone to write a program for me, but I would really appreciate some tips/general outline of how to do things. 1) First I want to make a grid that I can plot, and then transform by multiplying it with a matrix. Where's the best way to start? Should I use parametric_plot, or maybe it can be done with just a list of 2) Second I want to run the grid through a linear transformation. If I could just plot vectors and offset them (not having them start at the origin), I would only only have to iterate over a list of vectors to get the transformed vectors, but I'm not sure if this is a smart way to do it. Basically, is there a straight forward way to do this? It doesn't seem like it should be very difficult, if someone could give a rough outline of how to do this it would be greatly appreciated. Thanks. |
