[QUOTE=Chris J;461347]I hope this is the right spot to put these, I havent posted much, although I have been Lurking for a while, and you have helped me a great deal in the past, and For that I thank you.
1. Let I = √-1. Define a sequence of complex numbers by z1 = 0, z n+1 = z2n + I for n > or = to 1. In the complex plane, how far from the origin is z111 ?
If you really want some help you will need to improve the way these are posted.
You can't just cut and paste from a formatted document into the posting window. The hidden code for the formatting comes over and make the posting unintelligible in the reply.
Retype the questions rather than cut and paste, or at least go through an intermediary application (notepad say) that will strip off the formatting.
Better yet learn to use the LaTeX system here to type set the maths.
Finally only post one or two questions per thread
