#### About The Author of engineering mathematics stroud 7th edition pdf

K. A.Stroud was formerly Principal Lecturer in the Department of Mathematics at Coventry University, UK. He is also the author of *Foundation Mathematics* and *Advanced Engineering Mathematics*, companion volumes to this book.

Dexter J. Booth was formerly Principal Lecturer in the School of Computing and Engineering at the University of Huddersfield, UK. He is the author of several mathematics textbooks and is co-author of* Foundation Mathematics* and *Advanced Engineering Mathematics*.

Its unique programmed approach takes students through the mathematics they need in a step-by-step fashion with a wealth of examples and exercises. The engineering mathematics 7th edition ka stroud book demands that students engage with it by asking them to complete steps that they should be able to manage from previous examples or knowledge they have acquired, while carefully introducing new steps. By working with the authors through the examples, students become proficient as they go. By the time they come to trying examples on their own, confidence is high.

Aimed at undergraduates on Foundation and First Year degree programmes in all Engineering disciplines and Science. The Foundation section covers mathematics from GCSE onwards to allow for revision and gap-filling, and so means the book can be used for a range of abilities and all levels of access. Stuvera can help you download ka stroud engineering mathematics pdf online.
