The discussion focuses on determining the trajectory of the point (u, v) in the complex plane, given the complex function f(z) = u + vi, where u = sin(x) * cosh(y) and v = cos(x) * sinh(y). Participants suggest selecting specific points from the trajectory of z and substituting these values into the function to analyze the resulting trajectory of (u, v). The approach emphasizes practical application by evaluating the function at chosen points. This method aims to visualize how the transformation affects the trajectory in the complex plane. The conversation encourages hands-on exploration of complex analysis concepts.
