I am not especially talented in physics or math but I really enjoy it when I make progress. I believe it's super important for a philosophers understanding of metaphysical problems to understand physics. So in QM I really struggle to understand the use of complex functions because I don't really get what the complex plane is.   [Bo] N. Bourbaki, "Elements of mathematics.

The purpose of this book is to demonstrate that complex numbers and geometry can be blended together beautifully. This results in easy proofs and natural generalizations of many theorems in plane geometry, such as the Napoleon theorem, the Ptolemy-Euler theorem, the Simson theorem, and the Morley theorem. The book is self-contained - no background in complex numbers is assumed - and . The complex plane is a plane with: real numbers running left-right and; imaginary numbers running up-down. To convert from Cartesian to Polar Form: r = √(x 2 + y 2) θ = tan-1 (y / x) To convert from Polar to Cartesian Form: x = r × cos(θ) y = r × sin(θ) Polar form r cos θ + i r sin θ is often shortened to r cis θ. To plot a complex number, we use two number lines, crossed to form the complex plane. The horizontal axis is the real axis, and the vertical axis is the imaginary axis. See Example. Complex numbers can be added and subtracted by combining the real parts and combining the imaginary parts. See Example. Complex numbers can be multiplied and divided. In mathematics, the complex plane or z-plane is a geometric representation of the complex numbers established by the real axis and the perpendicular imaginary can be thought of as a modified Cartesian plane, with the real part of a complex number represented by a displacement along the x-axis, and the imaginary part by a displacement along the y-axis.

In complex analysis (a branch of mathematics), zeros of holomorphic functions—which are points z where f(z) = 0 —play an important role.. For meromorphic functions, particularly, there is a duality between zeros and poles.A function f of a complex variable z is meromorphic in the neighbourhood of a point z 0 if either f or its reciprocal function 1/f is holomorphic in some neighbourhood of.
