In re-writing the Solid Geometry the authors have consistently carried out the distinctive features described in the preface of the Plane Geometry. Mention is here made only of certain matters which are particularly emphasized in the Solid Geometry.

Owing to the greater maturity of the pupils it has been possible to make the logical structure of the Solid Geometry more prominent than in the Plane Geometry. The axioms are stated and applied at the precise points where they are to be used. Theo...

Arithmetic means dealing logically with facts which we know (about questions of number).

“Logically”; that is to say, in accordance with the “Logos” or hidden wisdom, i.e. the laws of normal action of the human mind.

For instance, you are asked what will have to be paid for six pounds of sugar at 3d. a pound. You multiply the six by the three. That is not because of any property of sugar, or of the copper of which the pennies are made. You would have done the same if the thing bough...

Het Nederlandse wiskundeonderwijs is volop in beweging. Curricula worden herzien en nieuwe digitale technologieën vinden hun weg naar het klaslokaal. Ook de wiskundedidactiek – de specifieke kennis over het leren en onderwijzen van wiskunde – ontwikkelt zich voortdurend. Over de huidige stand van zaken van dit vakgebied wil dit boek studenten, leraren, lerarenopleiders, auteurs en trainers informeren.

In drie delen biedt dit boek leraren handvatten om hun wiskundig-didactische vaardighed...

Deze inleiding tot de kansrekening richt zich op studenten van diverse studierichtingen zoals data-, ingenieurs- en natuurwetenschappen aan universiteit en hogeschool, maar ook op wiskundeleraren en eenieder die meer wil weten wat kansrekening inhoudt en hoe het wordt gebruikt. Inzicht en begrip staan voorop – hiertoe worden vele motiverende en leerzame voorbeelden en opgaven gegeven. Het boek behandelt de centrale begrippen en de belangrijkste kansverdelingen

Special attention has been paid to the requirements of the College Entrance Board. The book contains more material than is required for some first courses in Trigonometry, but the matter has been so arranged that the teacher can make such omissions as will suit his particular needs.

The trigonometric functions are defined as ratios; first for acute angles in right triangles, and then these definitions are extended to angles in general by means of coordinates.

The student is first taught to...

The three fixed lights, or windows, subsequently exchanged for our lesser luminaries, were explained one hundred and fifty years ago to signify "the three Persons, Father, Son, Holy Ghost; " and were used to find out the meridian, "when the sun leaves the south, and breaks in at the west window of the Lodge." While the "mossy bed," the ancient signs of disgust and recognition, as well as the primitive name of a Master Mason, are equally obscure at the present day; having been swept away, alon...

The present work is constructed on the same plan as my treatise on Plane Trigonometry, to which it is intended as a sequel; it contains all the propositions usually included under the head of Spherical Trigonometry, together with a large collection of examples for exercise. In the course of the work reference is made to preceding writers from whom assistance has been obtained; besides these writers I have consulted the treatises on Trigonometry by Lardner, Lefebure de Fourcy, and Snowball, an...

In the Chapter on ‘Propositions of Existence’ I have adopted a new ‘normal form,’ in which the Class, whose existence is affirmed or denied, is regarded as the Predicate, instead of the Subject, of the Proposition, thus evading a very subtle difficulty which besets the other form.

These subtle difficulties seem to lie at the root of every Tree of Knowledge, and they are far more hopeless to grapple with than any that occur in its higher branches. For example, the difficulties of the F...
