Ellina V. Grigorieva, Ph.D.

Professor of Mathematics

My book “Methods of Solving Complex Geometry Problems” at famous Sorbonne University bookstore, in Paris

 

 In September 2015 Springer published my new book "Methods of Solving Nonstandard Problems" and now it is available at http://www.springer.com/us/book/9783319198866

 

 

On August 19, 2013, I published my new book, Methods of Solving Complex Geometry Problems”, which is available at http://www.springer.com/978-3-319-00704-5.  

.

The book is a unique collection of challenging geometry problems and detailed solutions that will build students confidence in mathematics. By proposing several methods to approach each problem and emphasizing geometries’ connection with different fields of mathematics, this book serves as a bridge to more advanced problem solving. 

Methods of Solving Complex Geometry Problems will interest high school and college students to prepare for exams as well as anyone who enjoys an intellectual challenge and has a special love for geometry. It will appeal to instructors of geometry, history of mathematics and math education courses.
