The text has been written in a conversational style so that students will ﬁnd that they are not simply making reference to an encyclopedia ﬁlled with mathematical facts, but rather ﬁnd that they are in some way participating in or listening in on a discussion of the subject matter. Throughout the text the subject matter is presented using graphical, numerical, algebraic and verbal means whenever appropriate. Classical approaches have been judiciously combined with modern approaches reﬂecting new technology - in particular the use of the graphics calculator. The book has been speciﬁcally written to meet the demands of the Mathematics Standard Level course and has been pitched at a level that is appropriate for students studying this subject. The book presents an extensive coverage of the syllabus and in some areas goes beyond what is required of the student. Again, this is for the teacher to decide how best to use these sections. Sets of revision exercises are included in the text. Many of the questions in these sets have been aimed at a level that is on par with what...
