Differential Equations E-book Link© 2009 by Karl Hahn
The link below provides you with free access to a printable PDF file that contains J.W. Mellor's 1902 text on how to solve differential equations (now in the public domain) together with a supplement that I have prepared containing worked solutions to over a hundred of the exercise problems given in the text, my comments on the text, as well as other supplemental material. Altogether you get about 160 pages of material. Of course it is my hope that if you are taking a differential equations class or are interested in learning about this topic on your own, that you will find this material useful.
