MATSEC AM Pure Mathematics Complete Prep Course — Lesson 42: Rational functions and long division

Sarah defines a rational function as one polynomial over another non-zero polynomial, with the domain excluding every zero of the denominator, then separates proper from improper by comparing degrees. She drills polynomial long division beat by beat, insists on zero coefficients for missing powers, checks results by rebuilding the numerator and by the remainder theorem, and reads horizontal, oblique and vertical asymptotes straight off the divided form.
