Reading assignment: PpP 1.1-1.4
What is the complex conjugate of (1+3i)/(4-5i)?
(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.
