Inequalities

Triangle Inequality

or

Cauchy-Schwarz Inequality

Arithmetic, Geometric, and Harmonic Means

In other words, if A, G, and H are the arithmetic, geometric, and harmonic means, respectively, then H ≤ G ≤ A.

Hölder's Inequality

where

Chebyshev's Inequality

For a[sub]1[/sub] ≥ a[sub]2[/sub] ≥ ... ≥ a[sub]n[/sub] and b[sub]1[/sub] ≥ b[sub]2[/sub] ≥ ... ≥ b[sub]n[/sub],

Minkowski's Inequality

For positive a[sub]k[/sub], b[sub]k[/sub] and p > 1,

Bernoulli's Inequality

For x > -1, x ≠ 0, and integers n > 1,

A special case is

For 0 < p < q,

Young's Inequality

Let f be a continuous strictly increasing real-valued function on [0, ∞), with f(0) = 0 and as x approaches ∞, f(x) approaches ∞. Then if g is the inverse function of f, for any positive numbers a, b we have
