Find all distinct values for (a) (-1)/5 and (b) (1 - i). 6. Determine what conditions the complex numbers w and z must satisfy if z" is to have a finite (vs. infinite) number of distinct values. 4 7. Find all solutions to the complex equation 2=22. Express the solutions in both rectangular and polar form. 8. (a) Draw a sketch showing the region of the complex plane defined by lz + 3i-1| < 2. (b) Define a complex function == f(t) such that as the real parameter t is varied, z traces out the boundary of the region of part (a).
