Dennis G. Zill
Dennis Zill received a PhD in Applied Mathematics from Iowa State University, and is a former professor of Mathematics at Loyola Marymount University in Los Angeles, Loras College in Iowa, and California Polytechnic State University. He is also the former chair of the Mathematics department at Loyola Marymount University, where he currently holds a rank as Professor Emeritus of Mathematics. Zill holds interests in astronomy, modern literature, music, golf, and good wine, while his research interests include Special Functions, Differential Equations, Integral Transformations, and Complex Analysis.

In addition to new examples, figures and exposition, other new material includes an expanded table of Laplace transforms in Appendix C and a greater emphasis on the concepts of piecewiselinear differential equations and solutions that involve nonelementary integrals.

Many exercise sets have been updated by the addition of new problems. Some of these problems involve new and interesting mathematical models.

WebAssign: Zill's A FIRST COURSE IN DIFFERENTIAL EQUATIONS WITH MODELING APPLICATIONS continues to be fully supported by WebAssign. The powerful online learning, homework and course management system engages students in learning the math. WebAssign includes new endofchapter exercises and prebuilt assignments vetted by trusted subject matter experts, online learning tools like lecture videos and PowerPoint slides, plus robust course, section, assignment and question settings and online testing.

While this text is timetested and widely accepted, it has remained current with the addition of new exercises and the enhanced fourcolor presentation.

The fourcolor design adds depth of meaning to all of the graphics, particularly threedimensional pieces and visuals that involve multiple curves in a graph. The author directed the creation of each piece of art to ensure that it is as mathematically correct as the text.
