Do you know how to solve systems of Inequalities by using
Mathematica ( what is the method and commands ).
I need this method to solve the following problem
Given 1>a>b>c>0 and ac>=b^2 , Is there exist unique solution for x,y
such that x,y satisfy the following inequalities:
5) 1-4a+3b+3a^2-3ab-c+t>=0, where
t= x(-b+c-ab+a^2) + y(ac-ab-b(a^2)+a^3) +(b+b^2-a^2).
Thank you and please send your reply to
