WebIf z= x+iy, then a function f(z) is simply a function F(x;y) = u(x;y) + iv(x;y) of the two real variables xand y. As such, it is a function (mapping) from R2 to R2. Here are some examples: 1. f(z) = zcorresponds to F(x;y) = x+ iy(u= x;v= y); 2. f(z) = z, with F(x;y) = x iy(u= x;v= y); 3. f(z) = Rez, with F(x;y) = x(u= x;v= 0, taking values just ... WebAn argument of the complex number z = x + iy, denoted arg (z), is defined in two equivalent ways: Geometrically, in the complex plane, as the 2D polar angle from the positive real axis to the vector representing z. The numeric value is given by the angle in radians, and is positive if measured counterclockwise. Algebraically, as any real quantity
