MATSEC AM Pure Mathematics Complete Prep Course — Lesson 57: Conjugates and division

Sarah Mitchell teaches the complex conjugate as the tool that makes division work. She covers reversing the sign of the imaginary part, multiplying top and bottom by the conjugate of the denominator, the identity that z times its conjugate equals a squared plus b squared, the worked division of one plus two i by one minus i, the modulus formula, the product and quotient rules for moduli, and the real and purely imaginary tests.
