hi, can anybody solve the following equation for variable s with Mathematica? ((-(-1 + b))*R*beta)/(a - (-1 + b)*R*s)^sigma - (-s + w - w*tau)^(-sigma)==0 Solve doesn't work. I get this annoying error message. Solve::tdep: The equations appear to involve the variables to be solved for in an essentially non-algebraic way. I would like to get analytical solutions (numerical is not problem) to problems like this one.I know this one's easy done by hand but I have more cumbersome ones to deal with. Is there a package out there that can solve this analytically, or is this just impossible on computers? Thanks a lot. Juergen -- Using Opera's revolutionary e-mail client: http://www.opera.com/m2/
