Complex Analysis: a Self-Study Guide

This text is very useful, in my opinion.

The book's title implies it is a beginner's book and for self study. But the book assumes a lot of math knowledge, and has no detailed friendly explanations on the concepts. This is a good math book, but it would have been better if it was more explanatory on the basic concepts since it is titled as "Self Study Guide".I have been looking for math books with more detailed and friendly explanations on the concepts and applications into real world. But it is difficult to find math books in that category. The search for such math books continues.
