## Complex variables and applicationsThese classic textbooks, specializing in the techniques and applications of advanced mathematics to physical science and engineering, have endured as perennial standards for more than 60 years. The latest editions preserve the hallmark features that made Brown and Churchill a household name in advanced mathematics education-clear and concise exposition, interesting examples, and accessible level-while adding new enhancements, improved organization, and more modern examples and applications to serve another generation of students. |

#### Review: Complex Variables and Applications

User Review - Goodreadsnot too bad overall, but I found myself looking for other texts to see if they explained concepts better quite a bit. needed clearer explanations in places. Read full review

#### Review: Complex Variables and Applications

User Review - GoodreadsGot me through undergraduate Complex Anal, but I didn't really understand the stuff until reading Penrose. Uninspiring, but acceptable...for now. Read full review
