Cheat Sheet
- Formal Epsilon-Delta Definition -
The epsilon-delta definition provides a rigorous framework: limₓ→a f(x)=L means for every ε>0 there's a δ>0 such that |f(x)−L|<ε whenever 0<|x−a|<δ (MIT OpenCourseWare). Use the mnemonic "Epsilons Everywhere, Deltas Determine Distance" to recall roles. Mastering this makes any limits quiz questions feel like a breeze.
- One-Sided and Infinite Limits -
One-sided limits (limₓ→a❻ and limₓ→a❺) examine behavior from left or right; infinite limits describe unbounded growth (Stewart's Calculus). Sketching simple graphs helps you visualize asymptotic behavior - think "approach, never touch." This concept often appears in continuity quiz sections to test boundary insights.
- Limit Laws and Algebraic Rules -
The sum, product, quotient, and power laws let you break complex limits into manageable parts (Khan Academy). For example, limₓ→2(x²+3x)=limₓ→2 x² + limₓ→2 3x = 4 + 6 = 10. Memorize "Sally's Pretty Queen Plays" (Sum, Product, Quotient, Power) for speedy recall on your calculus limits quiz.
- Techniques: Factoring and Rationalizing -
When direct substitution yields 0/0, factor polynomials or rationalize conjugates to simplify expressions (University of California, Berkeley). For instance, limₓ→3 (x²−9)/(x−3) = limₓ→3 (x+3)=6 after factoring. Regular practice with a limit practice test solidifies these algebraic moves.
- Continuity and the Intermediate Value Theorem -
A function is continuous at a if limₓ→a f(x)=f(a); polynomials and sine/cosine are continuous everywhere (Paul's Online Math Notes). The Intermediate Value Theorem guarantees f takes every value between f(a) and f(b) - perfect for tackling limits and continuity questions. This principle underpins many real-world modeling problems.
