Reading assignment: PpP 1.1-1.4

What is the complex conjugate of (1+3i)/(4-5i)?


Consider the collection of all points in the complex plane that have the same magnitude--for the sake of discussion let's say the magnitude is 5. What's special about this group of points?

They form a circle with radius 5. See for example Fig. 1.1 in PpP.
