Every limit you evaluate in calculus reduces to just two foundational facts and four algebraic properties. This video builds your complete limit toolkit from the ground up, then demonstrates every piece in action by decomposing a complex rational expression step by step.
Key concepts covered:
• Fact 1: The constant rule — lim C = C for any constant
• Fact 2: The identity rule — lim x = a as x approaches a
• One-sided limits and when two-sided limits do not exist (1/x at zero)
• Vertical asymptotes and divergence to positive or negative infinity
• Property 1: Sum and difference rule for limits
• Property 2: Product rule and the constant multiple corollary
• Property 3: Quotient rule (and why you must check the denominator is nonzero)
• Property 4: Power rule, including roots as fractional exponents
• Conditions required for all limit properties to apply
• Full worked example: evaluating lim as x approaches 2 of (3x²+1)⁴/(x+5) = 28561/7 using only the six tools
