PREFACE This courseof analysisis intendedfor studentswho have a working knowledgeof the calculusand are readyfor a more systematic treatment. Only a quite exceptional mathematician will then be mature enoughfor an axiomaticdevelopment of analysis in metric spaces, and he can be left to teachhimself, The othersnormallyfollow a stlaightlorward course based on to provide theideaof a limit, and this book is an attempt such upperand a course.
I havestoppedshort of Cauchysequenccs, lowerlirnits, theHeine-Borel theorem anduniform convergence; in my experience many men understandthose topics more readilyif they are lcft to the next stage. Reuterand to Dr H. I am indebted Burkill for their carefulscrutinyof tlie manuscript.

The idea of a limit is also encountered in the chapter of algebraon progressions, whereit is 6een that certaingeJmetric progressions can be summed to in6nity.

This means that we canrnake the sum ofr termsas near to I as we like by taking t ;;; sufficiently largenumber. The notion of a limit restson that of afwctioz. The idea of a function in its turn restson that ofn,anber. The equation y : f x of the curve expresses a connectionbetween the number x and the number y. The scopeof mathematicalanalysls 'We cannow describe mathematicalanalysisasincluding those topics which dependon the notion of a limit. In a sense it does,and it is mainly by usage and tradition that analysishas come to denote a rather more formal or more 'advanced' presentation, witl greater attention to the foundations and more insistence on logical deduction.
The use of the word analysis has the advantageof clearly including the summation of infinite series which the schoolboy would reasonably regard as algebra rather than calculus. Operations which are complete in a finite number of steps, such as the evaluation of a determinant, belong to algebra,not to analysis.
The binomial theorem is a theorem of algebra if the index is a positive integer; othefwise it belongs to analysis. Geometryis a subject separate from analysis,developed from its own axioms. Its only impact on analysisis that we shall often find it suggestive and helpful to use geometricallanguageand illustrations. In the light of what we have said the subjecttrigonometry is seento fall into two parts. The solution of triangles,'height and. Results like. After a first coursein trigonometry, and other trigonometric functions, must be changed.
The sine originally definedas ratios of lengthsof lines, are seento be highly important functionsof analysis, and the sin x shouldbe asit will defined in termsof the variablex by the infinite series be in chapter6 of this book.
Someknowledge of the trigonometricfunctions and the exponentialand logarithmicfunctionstoo will be usefulin earlier chapters,but for the sole purpose of giving variety to the examples. The first topic for investigationis number. When treated with problems whichhave exhaustively this is a difficultsubject, roots both in mathernatics and in philosophy. As this is alrst of number as coursein analysiswe shall keep the discussion gives simpleas we can, so long as it a firm foundationfor the that will be setupon structureof later definitionsand theorems it, The readerwho wishesto go more deeplyinto the idea of.
Before embarking on a discussionof number, we must say what is meant by a ret. We often have to envisageall those personsor things having some assigned charaoteristicin com i British nationality who mon.
Illustrations are: all males of are at a given time at least 18 years and lessthan 60 years old, ii all mountain-tops on the Earth over 10, feet high, iii all positive integers, iv all equilateral triangles in a given plane. Suchcollectionsdeterminedby somedefining property we shall call sers.
The words classard aggregateare also used with the same meaning. We emphasisethat a set is known without ambiguity wheneverthe rules defining it enableus to say of any proposedcandidatewhether it is or is not a memberof the set. For instance,somereadersare included in the set i and others are not, but the rules are clear and no one is left in doubt. The sets i and ii are finite; with sufrcient knowledge and patience a complete list could be provided of the membersof eachof them.
The sets iii and iv on the other hand are infinite; in iii , however many positive integers we write down, there are more to follow. A defining property may be proposedwhich is riot possessed by anything. The correspondingset then has no members;it is empty ot null.
