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)
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 for which =.
In the realm of mathematics, a complex logarithm is an extension of the concept of logarithm to the complex numbers. The logarithm, \(\log_b(x)\), is a function defined for a positive base \(b\) and for real positive \(x\) where \(b\) is not equal to 1.
Definition: Complex Log Function. The function \(\text{log} (z)\) is defined as \[\text{log} (z) = \text{log} (|z|) + i \text{arg} (z), \nonumber \] where \(\text{log} (|z|)\) is the usual natural logarithm of a positive real number.
In this topic, we have discussed the logarithm of complex numbers, their definition, showed that log e z is a many-valued f n, discussed the General and principal value of log e z, and showed how it works. Moreover, mentioned some important properties of the logarithm and rules of the logarithm.
We define the multivalued complex logarithm and discuss its branches and properties. We also define complex exponential functions.
Main examples: I = [0; 2 ) or I = ( ; ] : arg[0;2 )( 3 ; i) = 2. arg( ; ]( = argI(z) has a cut line where the value jumps by 2 . Complex logarithms. To solve ew = z , for z 6= 0 : Let w = u + iv ; so ew = eueiv ; and write z = jzj e i : eueiv = jzj e i , eu = jzj ; eiv = ei : Infinitely many solutions w : u = log jzj ; v = + 2 k.
