WebMay 21, 2024 · The natural logarithm for θ ∈ ( − π, π) is written log ( z) = ln ( r) + i θ = u ( r, θ) + i v ( r, θ) so u ( r, θ) = ln ( r) and v ( r, θ) = θ. We know the derivative should result in 1 / z, but if we do the following: d d z log ( z) = ∂ u ∂ r ∂ r ∂ z + ∂ u ∂ θ ∂ θ ∂ z + i ( ∂ v ∂ r ∂ r ∂ z + ∂ v ∂ θ ∂ θ ∂ z) The partials involving r, θ and z are WebThe derivative of the natural logarithmic function (ln [x]) is simply 1 divided by x. This derivative can be found using both the definition of the derivative and a calculator. …
