My problem is a problem with two non-linear equations, they are non-linear with Exp. functions. My problem is that I can`t find any solution with different Solve menus or FindRoot. Solve[{(p2-380)Exp[p1-p2-20]/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2) +(p2-280)Exp[p1-p2-40]/((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120]) ^2) =(341-p1)/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2)+ (1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])(p1-156.88)+ (p1-141)(Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])/ ((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])^2), (p1-540)Exp[p1-p2-20]/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2)+ (p1-140)Exp[p1-p2-40]/((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])^ 2) =(p2-184.12)(Exp[p1-p2-20]/(1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])) -(p2-181)((Exp[p1-p2-20])^2)/((1+Exp[p1-p2-20]+2Exp[p1-90]+Exp[p1-80])^2) +(p2-281)Exp[p1-p2-40](1+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])/ ((1+Exp[p1-p2-40]+Exp[p1-130]+Exp[p1-110]+Exp[p1-120])^2)}] I would be very grateful if someone could tell me something how to progress this problem. -----------== Posted via Deja News, The Discussion Network ==---------- http://www.dejanews.com/ Search, Read, Discuss, or Start Your Own
