31.4.4 Solving Problems with Conjugate and Modulus
Core idea
Picture this: faced with an equation mixing z and z̄, either write z as x+yi or cleverly use z·z̄=|z|² to turn a tangle into something simple
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
