Proving z^5 is uniformly continuous on unit ball

Click For Summary
SUMMARY

The function f(z) = z^5 is uniformly continuous on the unit ball defined by |z| < 1. This conclusion is based on the established fact that any function continuous on a closed and bounded set is uniformly continuous on any of its subsets. Since the function is continuous within the region |z| ≤ 1, it follows that f(z) maintains uniform continuity throughout the unit ball.

Using what basis? It is a fact that if a function is continuous on a closed and bounded set, then it is uniformly continuous on any subset. If you are allowed to use that, it is sufficient to observe that [itex]z^5[/itex] is continuous on [math]|z|\le 5[/math].
