For one- or two-semester, sophomore-level courses in Differential Equations.The text introduces first order systems in the first chapter and uses them as the main focus for the treatment of ordinary differential equations covered in the first seven chapters. This allows an early and unified introduction of graphical and numerical methods along with analytical methods. The graphical and numerical theme is sustained in the chapters on partial differential equations and Fourier series.
