Complex number logarithm

Can you take the logarithm of an imaginary number?
is real..
Is logarithm defined for complex numbers?
In mathematics, a complex logarithm is a generalization of the natural logarithm to nonzero complex numbers.
The term refers to one of the following, which are strongly related: A complex logarithm of a nonzero complex number. , defined to be any complex number..
What is a logarithmic number?
logarithm: The power (or exponent) to which one base number must be raised — multiplied by itself — to produce another number.
For instance, in the base 10 system, 10 must be multiplied by 10 to produce 100.
So the logarithm of 100, in a base 10 system, is 2..
What is logarithm of a complex number?
The logarithm of complex number
Let z and w are two complex numbers, Connected by z= ew. ew= z, Then, we can say that w is a logarithm of z with base. w = logez..
What is the formula for the complex natural logarithm?
Let z=reiθ be a complex number expressed in exponential form such that z≠0.
The complex natural logarithm of zu220.
1. C≠0 is the multifunction defined as: ln(z):={ln(r)+i(θ+2kπ):k∈Z} where ln(r) is the natural logarithm of the (strictly) positive real number r
What is the logarithm form of a complex number?
Then logz=logr+iθ.
The complex logarithms are .. complex.
Any number w with ew=z is called a logarithm of z and a number can have (infinitely) many logarithms._{Sep 21, 2020}.
Where is the complex logarithm analytic?
Log(z) is analytic on C∖(−∞,0].
To make the function analytic you have to remove all non-positive real numbers from the complex plane.
To see where Log(z+1) ia anlytic you simply have to choose z such that z+1∉(−∞,0] which means z∉(−∞,−1].
So the answer is C∖(−∞,−1]..
Analytic, in a nutshell, means differentiable around a point.
On the negative real axis, complex log has a discontinuity across the real axis, which means it's not differentiable.
logi(z)=−2πilog(z), so it's just log(z) with a scaling factor.
The step function real part is the imaginary part of log(z) which wolfram is giving a branch cut along the real axis.
The natural logarithm of a number is its logarithm to the base of the mathematical constant e, which is an irrational and transcendental number approximately equal to 2.718281828459.
The natural logarithm of x is generally written as ln x, log_e x, or sometimes, if the base e is implicit, simply log x.

As a complex number z goes around the origin, the imaginary part of the logarithm goes up or down. This makes the origin a branch point of the function. For a Principal valueBranches of the complex The complex logarithm as a

In mathematics, a complex logarithm is a generalization of the natural logarithm to nonzero complex numbers. The term refers to one of the following, which are strongly related: A complex logarithm of a nonzero complex number. , defined to be any complex number.

A logarithmic number system (LNS) is an arithmetic system used for representing real numbers in computer and digital hardware, especially for digital signal processing.
