Review of TRIGONOMETRY Below is a set of problems that will be reviewed on Friday of the first week, in your recitation class. Try to do these problems on your own. Refer to Appendices A-6, and A-7 in your prescribed textbook that provide a brief review of trigonometry. Figure for Problems 1 and 2 1. Find sin 0. 5.00 m 1.50 m 2. Find 0 in degrees. e Figure for Problems 3 and 4 X 3. Find side y. 37 4. Find side x. 6.00 m Figure for Problems 5 and 6 5. Find tan 0. 6. Find cos 0. 4.00 m 2.50 m R 7. Find side R. 3.40 m 140 8. If sin 0 = 0, find two possible values for 0 in degrees. 9. If cos 0 = 0, find two possible values for 0 in degrees. 10. If tan 0 = 0.600, a) What quadrants could 0 lie in? b) What are two possible values of 0 in degrees? 1 1. If sin 0 = - 0.600, what are the two possible values of 0 in degrees? 12. If cos 0 = - 0.850, find which quadrants 0 could be in
