31.4 Conjugate and Modulus: a Pair of Mirror Images at Work
Point 1 of 4
31.4.1 The Conjugate: Flip It in the Mirror
Core idea
Picture this: reflect the arrow across the real axis so b becomes −b; the conjugate of a+bi is written a−bi, real part unchanged, imaginary part flipped
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
