Abstract
second edition of this book differs from the first in many respects. The number of pages has been increased from 188 to 348, and the explanatory matter is now in both German and English. There are now nineteen sections. The first contains a table of powers and a diagram of the surface z = xy, with two auxiliary diagrams for computing its ordinates. The second section contains tables ajnd graphs for performing various operations with complex numbers, including finding their reciprocals and square roots. Then follows a section on cubic equations, treated in a manner which will surprise the student whose know ledge of the subject has been gained only from the usual textbooks. The next two sections deal with certain equations containing trigonometrical functions.
