30 Απρ 2024 · The complex logarithm is an extension of the concept of logarithmic functions involving complex numbers (represented by log z). Mathematically, written as. log(z) = log(r ⋅ e iθ) = ln(r) + i(θ + 2nℼ) Here, z = r ⋅ e iθ = the complex number. r = |z| = the absolute value of z. θ = arg(z) = the argument of z and -ℼ < θ ≤ ℼ. ln(r ...
