Each assignment has a reading and a written part. Take reading the text seriously, as it will have a direct impact on your understanding of the subject matter. For the written part, do as many of the suggested problems as you can (preferably all!).
chapter 1: 4 (ii, iv, ix, xiii), 5 (i, vi, vii), 7, 9 (i, iv), 11 (iii, v, viii), 13.
chapter 2: 1 (ii), 2 (i) [there is a geometric picture behind this sum; can you discover it?], 5, 6 (i, iii), 12, 14.
chapter 3: 1 (i-v), 3 (i, ii, iv), 4, 5, 11 (a, b, c), 12, 13, 23, 25, 27.
chapter 4: 1 (iii, iv, v, viii), 3 (i, iii, iv, vii, viii, ix), 4 (i, ii, iii, viii), 5 (iii,iv), 6, 14, 17 (i,ii,v).
chapter 4, appendix 3: 1 [the trigonometric identity "cos(a-b)= cos a cos b + sin a sin b" is useful here], 3, 9 [don't try to be very precise; it suffices to get the main features of the graphs right].
chapter 5: 8, 15 (iii, v, vi, vii) [for (v) and (vii), either divide and multiply by 1 + cos x, or use the trigonometric identity 1 - cos x = 2 sin2(x/2)], 33 (i, ii).
chapter 6: 2 (do it only for problem 4-17 parts (i) and (ii)), 3, 13, 14.
chapter 7: 1 (i-iv), 2 (i, ii), 3 (ii), 5, 7, 10, 11.
chapter 8: 1.
chapter 9: 1, 3, 5, 11, 16, 26, 28.
chapter 10: 1 (i,ii,iii,v), 2 (i,ii,x), 5 (i,ii), 8, 24.
chapter 11: 1 (ii,vi), 2 (ii,vi), 3 (iv), 10, 15, 20, 21.
