0/0 Indeterminate Forms: Factoring & Conjugate Methods Explained

Описание: 📓 Interactive Notebook: https://ludium.ai/courses/calculus-1/...

When you plug in a value and get 0/0, your calculator says ERROR—but the limit actually exists. This video reveals why 0/0 is a clue, not a dead end, and teaches you the algebraic techniques to find the hidden answer.

You'll learn how factoring exposes common factors in polynomials and how conjugate multiplication eliminates stubborn square roots, turning impossible-looking limits into straightforward calculations.

📚 Key concepts covered:
• Why 0/0 signals a hidden common factor, not an unsolvable problem
• Step-by-step factoring technique for polynomial limits
• The conjugate method for rationalizing square root expressions
• Critical notation rules that prevent common errors
• Decision flowchart: when to factor vs. when to use conjugates

🔢 Examples worked through:
• lim(x→2) of (x²-4)/(x-2) = 4
• lim(x→1) of (x-1)/(√x-1) = 2
• lim(x→0) of (√(1+x)-1)/x = 1/2
