Limits Series Ep. 5 – Finding a Limit with Rationalizing Technique | AP Calculus AB

[Key Concepts] When direct substitution results in an indeterminate form like 0/0, algebraic methods can help simplify the expression. This problem uses the Rationalizing Technique, often applied when square roots are involved. Multiply both the numerator and denominator by the conjugate of the radical expression. This eliminates the square root in the numerator and allows simplification. After simplification, substitute the limit value again to find the actual limit. [Study Tip] Always recognize when a square root causes a 0/0 form. Rationalizing using the conjugate is a powerful tool—especially on the AP exam, where time-saving techniques matter! 📘 Selected from the textbook Calculus for AP by Ron Larson & Paul Battaglia. 📌 Subscribe here →    / @thecalculushero33   #RationalizingLimits #LimitTricks #CalculusTips #AlgebraicLimits #SquareRootLimits #APCalculusAB #MathShorts #STEMprep #CalculusHelp #maths #미국수학 #수학 #exam
