Solving Math Quadratic Equations and InequalitiesKaren KusanovichWendy LawsonNghi H. Nguyen
Solving inequalities is very like solving equations ... we do most of the same things.When solving equations we try to find points, such as the ones marked "=0" But when solving inequalities we try to find interval(s), such as the ones marked ">0" or "<0"So this is what we ...
1 LetAA,BB,CC,DDbe fixed positive numbers. Suppose that both inequalities A−1x−2xB>0,A−1x−2xB>0, C−1x−2xD>0,C−1x−2xD>0, have solution forx>0x>0. I want to find a regionUUinR+×R+R+R+(as large as possible, at least not a subset of{x=y}{x=y...

This note shows that we can recover any complex vector exactly from on the order of n quadratic equations of the form |aOE (c) a (i) ,x (0)>|(2)=b (i) , i=1,aEuro broken vertical bar,m, by using a semidefinite program known as PhaseLift. This improves upon earlier bounds in...
Linear Inequalities Quadratic InequalitiesSolving Linear InequalitiesA linear inequality is an inequality that can be expressed with a linear expression on one side and a 0 on the other side. Solving linear inequalities is as same as solving linear equations, but just the rules of solving ...
