This is a textbook for undergraduate engineering students. ... Many topics of the book are supplemented by historical remarks ... . (Lutz Recke, zbMATH 1497.35001, 2022) This new book on partial differential equations (PDEs) is primarily directed at upper-level undergraduate students in physics and engineering. It would also be appropriate for mathematics students either at that stage or in early graduate studies. ... the text is clear and well written. (Bill Satzer, MAA Reviews, October 31, 2022)
