2018-08-09 14:17:29 +0200 | commented answer | arrange an expression in powers of a variable Thanks! How to access the coefficients of each power? If you noticed, I am trying to use Sage for asymptotic analysis of DE's. Is there any guide/doc for this topic? |

2018-08-08 10:33:57 +0200 | asked a question | arrange an expression in powers of a variable I have the following code: which gives the output: How can I rearrange this expression in powers of "ep" parameter? i.e Then I want to get the coefficient for each power (which is a differential eq) and then pass it to the desolve. |
