Hi,(adsbygoogle = window.adsbygoogle || []).push({});

I have 2 questions regarding how to expand power series.

1). Find the power series expansion of Log z about the point z= i - 2

2). Expand the function 1/(z^2 + 1) in power series about infinity

Any help will be greatly appreciated. This is because I am totally unsure about what to do when they asked for an expansion of complex function or power series. And if possible, can you show me a somewhat detailed step by step explanation? I'm really sorry for the trouble. This is because I'm really clueless on how to even start.

Thank you so much
