31.4 Conjugate and Modulus: a Pair of Mirror Images at Work
Point 3 of 4
31.4.3 Modulus and Operations: |z₁z₂|=|z₁||z₂|
Core idea
Picture this: multiply two arrows and their lengths simply multiply too; the modulus of a product is the product of the moduli, and conjugation spreads across operations the same way
Module goal. We get a systematic feel for the conjugate and how it relates to the modulus, treating it as a central tool for working with complex numbers
