Abstract
In this chapter we meet three very important inequalities: Bernoulli’s Inequality, the Arithmetic Mean–Geometric Mean Inequality, and the Cauchy–Schwarz Inequality. At first we consider only pre-calculus versions of these inequalities, but we shall soon see that a thorough study of inequalities cannot be undertaken without calculus. And really, calculus cannot be thoroughly understood without some knowledge of inequalities. We define Euler’s number \(\mathrm{e}\) by a more systematic method than that of Example 1.32. We’ll see that this method engenders many fine extensions.
I speak not as desiring more, but rather wishing a more strict restraint.
