782 Foundations of <strong>Trigonometry</strong> 10.4.1 Exercises In Exercises 1 - 6, use the Even / Odd Identities to verify the identity. Assume all quantities are defined. 1. sin(3π − 2θ) =− sin(2θ − 3π) 2. cos (− π ) ( 4 − 5t =cos 5t + π ) 4 3. tan(−t 2 +1)=− tan(t 2 − 1) 4. csc(−θ − 5) = − csc(θ +5) 5. sec(−6t) = sec(6t) 6. cot(9 − 7θ) =− cot(7θ − 9) In Exercises 7 - 21, use the Sum and Difference Identities to find the exact value. You may have need of the Quotient, Reciprocal or Even / Odd Identities as well. 7. cos(75 ◦ ) 8. sec(165 ◦ ) 9. sin(105 ◦ ) 10. csc(195 ◦ ) 11. cot(255 ◦ ) 12. tan(375 ◦ ) ( ) ( ) ( ) 13π 11π 13π 13. cos 14. sin 15. tan 12 12 12 ( ) ( ) 7π 17π ( π 16. cos 17. tan 18. sin 12 12 12) ( ) ( ) 11π 5π ( 19. cot 20. csc 21. sec − π ) 12 12 12 √ √ 5 10 22.
