2019-01-16 22:27:41 -0500 | asked a question | How can I solve the following (linear) differential equation? I want Sage to solve this equation: $y'''-3y''+y'-5y=0$. Both and result in errors. |

2019-01-16 20:03:52 -0500 | answered a question | How to solve this system of equation in sage? Considering the notation of your first (general) example, simply copy the following code (as a script) and adjust $k$ as desired. Output of An alternative way would be to go via a matrix (which is notably faster). Output of This is indeed the same solution. |
