- AM-GM Inequality: For non-negative real numbers $x_1, x_2, ..., x_n$:
$$ \fracx_1 + x_2 + \dots + x_nn \geq \sqrt[n]x_1 x_2 \dots x_n $$
Methodology: Equality holds if and only if all terms are equal. This is often used to force symmetry in asymmetric equations.
- Cauchy-Schwarz Inequality:
$$ (\sum a_i^2)(\sum b_i^2) \geq (\sum a_i b_i)^2 $$
Methodology: Used to bound sums of products.
