Graphical Calculus

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. All up-to-date teachers of engineering and applied sciences generally now recognize the vast superiority of graphical over purely mathematical methods of im parting instruction of almost every description. The former are much more convincing to the student, because they appeal to the eye, the training of which is one of the chief objects to be aimed at in the education of an engineer. There is no doubt that this method is capable of great extension with advantage. In this little book, for instance, we see graphical con structions of a very simple character employed to teach what, to the beginner, are somewhat abstruse mathe lmatical principles.
