Practical Mathematics: Including-Trigonometry Trigonometry and an Introduction to the Calculus, a for Fr Elementary, Secondary and Technical Schools (Classic Reprint) - Tapa blanda

Reseña del editor

So many text-books on Algebra have appeared during the last few years that the publication of yet another requires some justification. In the present volume, the processes of Algebra are established in a practical way, and their application to Science and Mensuration is made a prominent feature Although some boys find a certain satisfaction in juggling with meaningless symbols, the application of Algebra to practical problems rouses their interest and fills them with enthusiasm. The author finds encouragement in a recent address to theM athematical Association by Professor Whitehead, F.R.S., which contained the following: Algebra is the intellectual instrument which has been created for rendering clear the quantitative aspects of the world. Graphs are an important feature of this book, and they arc not abandoned as soon as their algebraic significance becomes evident, but are employed to illustrateand establish many important relations. The treatment is in accord with the recent suggestions of theB oard of Education. Ratio and Proportion being of such importance in the teaching of Science, arc given an early place in the scheme. Trigonometry is introduced. Experience shows that when students recognise that trigonometrical terms are merely algebraic symbols, the terrors of the subject disappear. Other special characteristics are :I. Academic treatment has been avoided as far as possible. II. The requirements of pupils who will engage in technical work on leaving school, but who will not have the opportunity to attend aU niversity, have been borne in mind. III. Artificial problems have here given place to more useful applications.
