The authors of this textbook have little skill in writing or editing their own work. The chapters are filled with examples that have blatantly incorrect answers, which only serves to confuse.
The book does give u a general idea of Maths involved in BME, but imho, this book offers poor explanations, way too many errors, not enough details/info on various topics. I wouldn't waste my money on this.
The book was in a fine condition. The only problems were a few tears on the edges which were mostly covered up by a cheap book cover.
