Hi cooljackiec;

|5-12i|+|3-4i| = 13 + 5 = 18

a) Suppose we graph every point z  in the complex plane such that |z| = 4. What shape results?

b) What is the graph of the equation |z-2i| = 3

Compute |5-12i|+|3-4i|.

hi scientia

Nice solution.  smile

So where are the imaginary numbers?

Perhaps you have to imagine them.  roflol
