This detailed guide will take you through various applications of complex logarithm, underscoring its importance in practical settings. Further, learn how to resolve complex logarithm problems and how these functions are implemented in the realm of engineering.
Because equation 3.21 yields logarithms of every nonzero complex number, we have defined the complex logarithm function. It is defined for all z 6= 0, and because argz is determined only to a multiple of 2π, each nonzero complex number has an infinite number of logarithms. For example, log(1+i)=ln √ 2+(π/4+2kπ)i =(1/2)ln2+ (8k +1)πi/4.
Example: Use the definitions of cos(z ) and sin(z ), eiz. + e−iz. cos(z ) = sin(z ) = 2 , to find (cos(z )) and (sin(z )) . Show that Euler’s formula also works if. eiz − e−iz. 2i . θ is complex.
