name: First trigonometry problems due Thursday, September 29, 2011 please show relevant work to get full credit for each problem 6. Write down the values of the six trigonometric functions of the angle A: ( sin A, cos A , etc.) 5 A 8 7. Suppose that tan A = 4 7 (a) Draw a right triangle showing the angle A and side lengths 4 and 7 in the correct positions. (b) Use the Pythagoras theorem to find the length of the last side of the triangle. (It’s OK to leave this as a square root) (c) Find the values of cos A and sin A.
