Unformatted text preview: MAC 1147 Review 4, Fall 2010 Exam 4 covers Lectures 27-35 The problems with an astroid ( ) are from lectures 36 and 37. They will be in the final exam, but not exam 4. 1. If (4 , 8) is on the terminal side of an angle u1D703 in standard position, find sin u1D703 , cos u1D703 and tan u1D703 . 2. In a right triangle, if sin u1D703 = 1 4 , find sin(90 u1D703 ), cos( u1D703 + 2 u1D70B ), cot u1D703 and tan( u1D703 ). 3. If sec( u1D703 ) = 17 and sin u1D703 < 0, find tan u1D703 and csc u1D703 . 4. If u1D703 is in standard position such that its terminal side lies on the line 3 u1D465 2 u1D466 = 0 with restriction u1D465 0, find the exact value of cos u1D703 . 5. If sec u1D703 = 2 and u1D703 is an acute angle, find the exact value of tan u1D703 sin u1D703 + tan u1D703 cot u1D703 (1 + tan 2 u1D703 ) + (1 sin 2 u1D703 ) 6. Which of the following pairs of functions have the same graphs? (a) u1D466 = sin u1D465 and u1D466 = cos uni0028.alt02 u1D465 u1D70B 2 uni0029.alt02 (b) u1D466 = cos u1D465 and u1D466 = sin uni0028.alt02 u1D465 u1D70B 2 uni0029.alt02 (c) u1D466 = sin( u1D465 u1D70B ) and u1D466 = sin u1D465 7. Find at least two equations for each graph....
