Desigualdades
\(a,b,c,d>0\)
- \(a+\frac{1}{a}\geq?\)
- \(\frac{a+b}{2}(\geq ou\leq?)\sqrt{ab}\)
- \(\frac{a+b}{2}(\geq ou\leq?)\sqrt{ab}\) (outra versão)
- \(2ab(\geq ou\leq?)a^{2}+b^{2}\)
- \(ab+bc+ca(\geq ou\leq?)a^{2}+b^{2}+c^{2}\)
- \(\frac{a}{b}<\frac{c}{d}\Rightarrow\frac{a}{b}<?<\frac{c}{d}\)
- Desigualdade de Cauchy-Schwarz \(|px+qy|\leq?\)
