2015-03-16 17:06:26 +0200 | asked a question | Questions about the parameters in the output of solve I am writing a program that, among other things, has to solve many systems of polynomial equations (of degree <= 3) determined by the data entered by the user. Each system of equations consists of 3 equations in 3 variables. Sometimes the equations in a given system are redundant, and therefore the output of solve contains parameters (free variables). Is there any way to know which variables in the output of solve are the parameters (without having to look at the actual output in Sage)? Here is a simple example. The output is How do I know which variable is the free variable in this case (without looking at the output)? Is it true that the free variable(s) in the output of solve will always be the "last variable(s)" (in the alphabetical order), I understand that the Thanks, Aldo |
