Limits in complex numbers and functions

Click For Summary

Homework Help Overview

The discussion revolves around limits involving complex numbers and functions, specifically focusing on three distinct limit problems. The first limit involves a sequence with a complex number raised to the power of n, the second limit concerns the behavior of a trigonometric function divided by a polynomial as z approaches zero, and the third limit examines a complex function as z approaches a specific complex number.

Discussion Character

  • Mixed

Approaches and Questions Raised

  • Participants explore the divergence of the first limit and question how to prove it. There is discussion about the application of known limits from real calculus to the second limit, and the third limit raises concerns about the indeterminate form 0/0. Some participants suggest using logarithmic properties and power series expansions to analyze the limits further.

Discussion Status

Participants are actively engaging with the problems, offering insights and corrections. Some have begun to clarify their understanding of the limits, while others are still grappling with the implications of their findings. There is a recognition of the need for further exploration of the limits, particularly in how to handle the indeterminate forms and the application of L'Hôpital's rule.

Contextual Notes

There is a noted confusion regarding the notation in the first problem, which has implications for its convergence. Participants are also considering the nature of complex functions and how traditional calculus techniques apply in this context.

I think I got it.
I ended up with
(1-i√3)/6
Sound right?? Should be if I did all the calculations right.

That looks like what I got.

Just checked on WOLFRAM. Correct! VICTORY!
