Hello group, I've been eyeing Sage for a while-- it has always struck me as a wonderful project. Recently I have started trying to use it for homework assignments and have had very encouraging results so far.
However, tonight I have been trying to solve an open channel flow problem which requires me to find the roots of: y^3 - 1.39027132807289 * y^2 + 0.090610488164005 == 0 Both the symbolic solvers in maxima and sympy return complicated expressions involving imaginary numbers. I have tried yacas and Wolfram|Alpha-- both of which return real valued solutions (although yacas does require the Solve() function to be wrapped in the N() function). find_root() does return the correct answers-- but in this case both positive roots are of interest so it would be nice to recover them both at the same time. Is there an option to solve() that I have overlooked that would help in this situation?
