B.4 Solving Inequalities Algebraically and Graphically
www.rbrhs.org1. When each side of an inequalities is multiplied or divided by a negative number, the direction of the inequality symbol must be reversed in order to maintain a true statement.-2 < 5 (-3)(-2) > (-3)(5) Reverse sign, Multiply by -3 6 > -15 2. Two inequalities that have the same solution set are equivalent inequalities. x + 2 < 5 and x < 3
1 Proofs by Induction - Cornell University
www.cs.cornell.eduProceeding as before, but replacing inequalities with equalities, we have fn+1 = fn +fn 1 = r n2 +r 3 = rn 3(r +1) = rn 3r2 = rn 1; where we used the induction hypothesis to go from the rst line to the second, and we used the property of r that r2 = r+1 to go from the third line to the fourth. The last line is exactly the statement of P(n+1).

web.stanford.eduRestriction of a convex function to a line f : Rn → R is convex if and only if the function g : R → R, g(t) = f(x+tv), domg = {t | x+tv ∈ domf} is convex (in t) for any x ∈ domf, v ∈ Rn can check convexity of f by checking convexity of functions of one variable
