8. Draw a reference triangle for the relation =3tan , and express sin 0 and seco in terms of r . Answer for 8. sin 0 = sec 0 = 9. Find the limit of the sequence an = n . [In(2n + 1) - In(2n)] . Write 'DIVERGES' if the sequence diverges. PART B (64 marks) In this part you are required to provide full solutions and to show all your work. A correct answer obtained with false reasoning or with no reasoning will not receive any marks. Each question is worth 16 marks. 1.
