tan(10") + tan(20) 7. Letra 1 - tan(109) tan(20) a) Writer as a single function of sine, cosine, or tangent. b) Without the aid of a calculator, find the exact value of 2. 8. Given the following information i) sin(A) = , and the terminal side of A lies in Quadrant I and ii) sin(B) = 24 and the terminal side of B lies in Quadrant II, find the exact value of each of the following trigonometric functions, a) cos(A+B) b) sin(A + B) c) cot(A+B) d) sec(-A-B) 9. Given that cot(0) = 9 and the terminal side of 6 lies in Quadrant III, find the exact value of each of the following trigonometric functions. a) cos(28) b) sin(20) c) tan (20) 10. Use the appropriate half-angle formula to find the exact value of sin(75) 11. Express cos(56) + cos(70) as a product of sines and/or cosines. cos(2) - cos(y) 12. Verify the identity: =-tan sin(x) + sin(y) 13. Find all solutions to 7 sin(1) + 1 = 5 sin(x). 14. Find all solutions to 2 sin(2x) + 1 = 2 on [0, 27). 2
