Excerpt from Graphic Algebra: An Elementary Text Book for College Students, Graphs In chapter VIII, the general formulae for the nth roots of +1, are arrived at by easy steps from previous geometrical considerations, without the introduction of Demoivre's Formula, or of the exponential form of the complex quantity. The next two chapters discuss complex quantities, and the Argand Diagram in which are given some of the simple principles of the calculus of complex quanti ties and some simple complex functions. The geometrical rules for complex multiplication and division constitute a novel feature which will do much toward simplifying the graphical representation of complex functions. The student cannot become too thoroughly familiar with these rules. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
