10.2. DOUBLE-ANGLE IDENTITIES 457 1 − tan 2 x 1+tan 2 x = 1 − tan2 x sec 2 x = 1 sec 2 x − tan2 x sec 2 x =cos 2 x − ( sin2 x cos 2 x ) ( 1 cos 2 x ) =cos 2 x − sin2 x cos 2 x · cos2 x 1 =cos 2 x − sin2 x ✘cos ✘✘ 2 x · ✘✘ cos 2✘ x 1 =cos 2 x − sin 2 x This is one of the identities for cos(2θ) so we can stop and simply state cos(2x) = cos 2 x − sin 2 x
458 CHAPTER 10. TRIGONOMETRIC IDENTITIES AND EQUATIONS Exercises 10.2 In each problem verify the given trigonometric identity. 1. 2sinx cos x cos 2 x−sin 2 x =tan(2x) 2. sec(2x) = sec2 x 2−sec 2 x 3. sin(2x) csc x =2cosx 4. 2cosx sin(2x) = csc x 5. cos(2x) x sin x +sinx =cot sec x 6. sin x+sin(2x) sec x+2 =sinx cos x 7. (sin x +cosx) 2 =1+sin(2x) 8. (sin 2 x − 1) 2 =sin 4 x +cos(2x) 9. 2cosx− cos(2x) cos x = sec x 10. 1+cos(2x) 1−cos(2x) =cot2 x 11. cos(2x) sin 2 x =cot2 x − 1 12. cos(2x) sin 2 x = csc2 x − 2 13. 15. 17. cot x−tan x x−cot x) cot x+tan x =cos2x 14. sin 2x =2(tan tan 2 x−cot 2 x 2 cos 2x sin 2x =cotx − tan x 16. tan 2x = 2 cot x−tan x sin x 1+cos x +1+cos x sin x = 2 csc x 18. tan x +cotx = 2 csc(2x) 19. cos(2x) = cot2 x−1 cot 2 x+1 20. sin(2x) = 2tanx 1+tan 2 x 21. 23. 2sin 2 x sin(2x) +cotx = sec x csc x 22. sec2 x cos(2x) =sec 2 x − 2tan 2 x cos(2x) sin x +sinx = csc x − sin x 24. 2tanx−sin(2x) 2sin 2 =tanx x
