Question: Solve command gives 0



I am using Maple 17 to solve some equations. I am solving these equations with the solve command. There are some bounds on the parameters so I am including these inequalities. I have 4 variables, so I solve for 3 to get them in terms of the last one.

It returns piecewise solutions as per the inequalties as I hoped.

However for two ranges of the inequalities I get [] which I assume means no solution.

For another range I get an expression for each of my paramters.

For the final range I get 0 . What does this 0 mean and what do the [] mean?


I wondered if 0 meant that all paremeters equalling zero was a solution, but this is false.
