Analysis
Overview
Section titled “Overview”Analysis problems tend to hinge on precise estimates. Turn vague limiting behavior into inequalities, isolate monotonicity, and keep compactness or continuity in mind when extrema exist.
Checklist
Section titled “Checklist”- Identify whether the problem is local, global, or asymptotic.
- Prove monotonicity before trying to compute a limit.
- Use bounding sequences or squeeze arguments.
- Look for compact intervals when maxima or minima are needed.
- Translate continuity into sign changes or intermediate values.
Common moves
Section titled “Common moves”- Compare a sequence to a simpler one.
- Use Taylor expansion only with controlled error terms.
- Apply mean value theorem, intermediate value theorem, or extreme value theorem.
- Turn integrals into upper and lower estimates.
