  1. Aim #5.1: How do we verify the trigonometric identities? • The Fundamental Identities –

  2. Example 1: Changing to Sines and cosines • Verify the identity: Sec x cot x = csc x

  3. Check for Understanding: • Verify the identity: csc x tan x = sec x

  4. Example 2: Changing to Sines and Cosines • Verify the identity: sin x tan x + cos x = sec x

  5. Check for Understanding: • Verify the identity: cos x cot x + sin x = csc x

  6. Example 3: Using Factoring to Verify an Identity • Verify the identity: cos x – cos x sin2 x = cos3 x

  7. Check for Understanding: • Verify the identity: sin x –sin x cos2 x = sin3 x

  8. Example 4: Using Two Techniques • Verify the identity:

  9. Check for Understanding: • Verify the identity:
