Preface This textbook has been written for students in Years 11 and 12 taking the course previously known as '3 Unit Mathematics', but renamed in the new HSC as two courses, 'Mathematics' previously called '2 Unit Mathematics' and 'Mathematics, Extension 1'.
The book develops the content at the level required for the 2 and 3 Unit HSC examinations. Schools will, however, differ in their choices of order of topics and in their rates of progress. Although these Syllabuses have not been rewritten for the new HSC, there has been a gradual shift of emphasis in recent examination papers.
The interdependence of the course content has been emphasised. Graphs have been used much more freely in argument. Structured problem solving has been expanded. There has been more stress on explanation and proof. This text addresses these new emphases, and the exercises contain a wide variety of different types of questions.
In particular, both those who subsequently drop to 2 Units of Mathematics, and those who in Year 12 take 4 Units of Mathematics, will find an appropriate level of challenge.
We have written a separate book, also in two volumes, for the 2 Unit 'Mathematics' course alone. We would like to thank our colleagues at Sydney Grammar School and Newington College for their invaluable help in advising us and commenting on the successive drafts, and for their patience in the face of some difficulties in earlier drafts.
We would also like to thank the Headmasters of Sydney Grammar School and Newington College for their encouragement of this project, and Peter Cribb and the team at Cambridge University Press, Melbourne, for their support and help in discussions.
Finally, our thanks go to our families for encouraging us, despite the distractions it has caused to family life. The book covers the 2 Unit and 3 Unit content without distinction, because 3 Unit students need to study the 2 Unit content in more depth than is possible in a 2 Unit text. Nevertheless, students who subsequently move to the 2 Unit course should find plenty of work here at a level appropriate for them. The Exercises: No-one should try to do all the questions! We have written long exercises so that everyone will find enough questions of a suitable standard each student will need to select from them, and there should be plenty left for revision.
The book provides a great variety of questions, and representatives of all types should be selected.
Each chapter is divided into a number of sections. There is little point in proceeding without mastery of this group. It contains more substantial questions, questions requiring proof or explanation, problems where the new content can be applied, and problems involving content from other sections and chapters to put the new ideas in a wider context.
Later questions here can be very demanding, and Groups 1 and 2 should be sufficient to meet the demands of all but exceptionally difficult problems in 3 Unit HSC papers. Some are algebraically challenging, some establish a general result beyond the theory of the course, some make difficult connections between topics or give an alternative approach, some deal with logical problems unsuitable for the text of a 3 Unit book.
Students taking the 4 Unit course should attempt some of these. The Theory and the Worked Exercises: The theory has been developed with as much rigour as is appropriate at school, even for those taking the 4 Unit course. This leaves students and their teachers free to choose how thoroughly the theory is presented in a particular class.
The following year, he completed his doctoral studies in theoretical physics under Ralph H. During his studentship, he split his time working at Cambridge and with Niels Bohr in Copenhagen.
In , Bhabha published a paper in the Proceedings of the Royal Society, Series A , in which he performed the first calculation to determine the cross section of electron-positron scattering.
Electron-positron scattering was later named Bhabha scattering , in honour of his contributions in the field. In , with Walter Heitler , he co-authored a paper, "The Passage of Fast Electrons and the Theory of Cosmic Showers"  in the Proceedings of the Royal Society, Series A, in which they used their theory to describe how primary cosmic rays from outer space interact with the upper atmosphere to produce particles observed at the ground level.
Bhabha and Heitler then made numerical estimates of the number of electrons in the cascade process at different altitudes for different electron initiation energies. The calculations agreed with the experimental observations of cosmic ray showers made by Bruno Rossi and Pierre Victor Auger a few years before.
Bhabha later concluded that observations of the properties of such particles would lead to the straightforward experimental verification of Albert Einstein 's theory of relativity. In , Bhabha was awarded the Senior Studentship of the exhibition , which helped him continue his work at Cambridge until the outbreak of World War II in He accepted an offer to serve as the Reader in the Physics Department of the Indian Institute of Science , then headed by renowned physicist C.
Bhabha selected a few students, including Harish-Chandra , to work with him. Later, on 20 March , he was elected a Fellow of the Royal Society. With the help of J. Tata , he played an instrumental role in the establishment of the Tata Institute of Fundamental Research in Mumbai.
Career[ edit ] Starting his nuclear physics career in Britain , Bhabha had returned to India for his annual vacation before the start of World War II in September War prompted him to remain in India and he accepted a post of reader in physics at the Indian Institute of Science in Bengaluru , headed by Nobel laureate C.
As part of this vision, Bhabha established the Cosmic Ray Research Unit at the Institute, began to work on the theory of point particles movement, while independently conducting research on nuclear weapons in During this time, he intensified his lobbying for the development of nuclear weapons. Soon after the Sino-Indo war , Bhabha aggressively and publicly began to call for the nuclear weapons.
