Overview

Olympiad inequalities require proof structure, not just computation. Learn to choose substitutions that make known inequalities applicable.

Key Ideas

  • Homogenize expressions to balance degrees.
  • Substitute a=xya=xy, b=yzb=yz, c=zxc=zx or a=xya=\frac{x}{y} in symmetric problems.
  • Identify equality cases to guide transformations.
