Book Description

Excerpt from Logarithmic and Trigonometric Tables: Five-Place and Four-Place I have sought to use symbols and equations only in those cases where I could see no gain in spelling out their meaning. The practical teacher may rest assured that in this treatise there are no breaks in the continuity of reasoning, nor need he fear that there is any lack of training in demonstrative processes. Fitting schools will naturally be solicitous to know if the class using such a text would be prepared to pass such college entrance examinations as may be tried. Of course it is impossible to predict the questions that may be asked in future; but an actual test has been made of all available college entrance examination papers and only one theorem was discovered that has been omitted from the present work, and that one might be called an original since none of the three texts recommended by this particular University contained that theorem. Attention is called to the solution of problems. Ordinarily the problem is presumed to be solved, and then a demonstration is given to show that the solution was correct. This does not appear to me to be in the line of discovery. I have in all cases started with a statement of those known facts which plainly suggest the first step in the solution, then introduced the next step, giving the construction in connection with each stated fact, so that with the completed construction goes its own demonstration and the student sees the road along which he travelled, and understands from the beginning why he started upon it. - author's note.
