comment Find all complex and real roots of higher degree polynomials, given one root
Hint: If you know one more root, you can divide out and then obtain a quadratic, whose roots are solved for by the quadratic equation. Remember that complex roots come in pairs...

comment Algebraic topology - angle function
You can find a branch of logarithm, it just may not be holomorphic. But the function $g(z)$ only needs to be continuous.

comment Example of Something That's Not A Manifold
A manifold is a set with a certain structure, so every set is automatically not a manifold without that structure. Do you mean to ask for topological spaces that aren't manifolds, or subsets of $\mathbb{R}^n$ that aren't manifolds, etc.?
