Dear Friends, I tried to solve the following system of nonlinear inequalities with Mathematica 5.0: F < (1/2)*[a^(x/(2 - x))]*[x^(2/(2 - x))] && (2*a*B)^(x/2) + F - B > (2*a*F)^(x/2) && F > B > 0 && 0 <= a <= 1 && 0 < x < 2. I tried with Reduce, SolveInequality, SemiAlgebraicComponent, FindInstance, but all these function do not solve it. I tried to substitute x for some fixed value, but again I cannot solve it. The only value that I can substitute for x is 1, and in this case the solution is an empty space. I may be happy if I find a value that solves the system, although I really need for which inetervals in the variable this system is not an empty space. Hope some nice Mathematica expert can help me.
