Page 185 - Whatever equivalent form is discoverable in arithmetical algebra considered as the science of suggestion, when the symbols are general in their form, though specific in their value, will continue to be an equivalent form when the symbols are general in their nature as well as in their form (Peacock 1833, pp.
Page 206 - But it is said that the symbol = here designates symbolical equivalence. The truth of this assertion depends on the definition of this phrase, and without doubt many arbitrary definitions might be given, in accordance with which the Binomial Theorem might be considered to hold for divergent series.
Page 185 - ... from arithmetical to symbolical algebra, we now make the following hypotheses : (1.) The symbols are unlimited, both in value and in representation. (2.) The operations upon them, whatever they may be, are possible in all cases. (3.) The laws of combination of the symbols are of such a kind as to coincide universally with those in arithmetical algebra when the symbols are arithmetical quantities, and when the operations to which they are subject are called by the same names as in arithmetical...

Page 187 - ... for such reasons, to notice it somewhat in detail. If the operations of algebra be considered as general, and the symbols which are subject to them as unlimited in value, it will be impossible to avoid the formation of divergent as well as of convergent series: and if such series be considered as the results of operations which are definable, apart from the series themselves, then it will not be very important to enter into such an examination of the relation of the arithmetical values of the...

Verschiebt man dann diese Punkte, indem man die Segmente (anb), (bpc), (cqd), (dma) ungeändert läßt, bis sie auf einem Kreise liegen, so hat man nach § 50, 1. die Fläche des Vierecks ab cd vergrößert; die übrigen Teile der Fläche F und der Umfang von s sind dadurch nicht geändert. Strenge Beweise des Satzes, daß der Kreis unter allen Figuren gleichen Umfanges den größten Inhalt hat, geben F.

Page 189 - ... within any conceivable distance of D. By the second part of the theorem (197), it is proved that arc BO : arc BF : : angle BCO : angle BCF. Now, although the arc BD is itself incommensurable with BF, yet it is the limit of the arcs BO, and the angle BCD is the limit of the angles BCO. Therefore, since whatever is true up to the limit is true at the limit, arc BD : arc BF : : angle BCD : angle BCF.
