Complex numbers are the points of \({\mathbb R}^2\) . Each complex number \(z = a + \operatorname {i} b\) with \(a, \, b \in {\mathbb R}\) is uniquely defined by the Cartesian coordinates \((a,b) \in {\mathbb R}^2\) . The plane \({\mathbb R}^2\) can also be imagined as a union of circles around the origin.

摘要

Complex numbers are the points of \({\mathbb R}^2\) . Each complex number \(z = a + \operatorname {i} b\) with \(a, \, b \in {\mathbb R}\) is uniquely defined by the Cartesian coordinates \((a,b) \in {\mathbb R}^2\) . The plane \({\mathbb R}^2\) can also be imagined as a union of circles around the origin.
