WitrynaIn mathematics (particularly in complex analysis), the argument of a complex number z, denoted arg(z), is the angle between the positive real axis and the line joining the origin and z, represented as a point in the complex plane, shown as in Figure 1. It is a multivalued function operating on the nonzero complex numbers.To define a single … Witryna4 Answers. Yes nothing special. If f and g are real functions then ∫ ( f + i g) = ∫ f + i ∫ g. Nothing special for situations like this, but if, for example, you're integrating ( 1 / x) d x not along the line from 0 to 4, but along a circle that winds once counterclockwise around 0, then you may need something more sophisticated.
