Hi, I really need help on both parts of this complex analysis question. Thanks! 1. Let be a complex number and let 12=C 1.R>o be the complement in C to all real positive multiples of . (a) Show that the function 2 H 23 has a continuous inverse function, called 37, on N. (Hint: polar coordinates might help). Prove that there are exactly three different such continuous functions. Deduce that there is no continuous extension of 37 on all of...
