Preface

Abstract

Reference has been already made in the general preface to the purpose of. this Division of the work as a whole. The choice of topics has been such as will promise the most immediate aid to those whose mathematical preparation may not have included all the methods conveniently and usefully employed in the development of various phases of aerodynamic theory. In all cases the treatment has, of necessity, been partial and confined to the more elementary phases of the subject. No attempt has been made to include the subject of differential equations, this for the two reasons: first, the very considerable space which would be required for a treatment covering in any reasonable degree the use of this mathematical discipline in its many applications to the various problems arising in aerodynamic theory and second, the growing extent to which this subject is now found in engineering and technical curricula and the many excellent text books which are available for the interested reader.
