need some urgent help with basic complex variables (no proofs)
Hi:
can someone give me examples of the following? (no proofs needed)
1. a non-zero complex number z such that Arg(z^2) "not equal to" 2 Arg z
2. a region in C which is not a domain
3. a non-empty subset of C which has no accumulation points
4. a continuous function f: C -> C which is not differentiable anywhere
5. an entire function which is not a polynomial.
thanks a lot in advance!
