2017-07-21 22:34:13 +0100 | asked a question | 3d plot in vector format: still using matplotlib? In 2012, the best way to create a vector image in Sage from a three-dimensional plot was to call matplotlib, as the answers to Question 9057 show Is this still the case? Or are there other work-arounds now? |

2017-07-10 16:45:34 +0100 | asked a question | Collecting coefficients of derivatives I have a complicated expression involving derivatives of a function, and I'd like to collect all of the first, second, third, etc. derivatives. For example, my expression starts: and I would like to rewrite that part as How do I tell Sage to do this? |
