  1. 7.1: Trigonometric Identities TSW understand and be able to apply the fundamental trigonometric identities and prove trigonometric identities at an 85% mastery level as demonstrated by discussion and practice.

  2. Fundamental Identities

  3. Simplifying Expressions Ex: Simplify the expression Ex: Simplify the expression Pg. 540 (1- 21 Odd)

  4. Proving Trig. Identities 1. Start with one side (either left or right). Then transform it into the other side. 2. Use known identities. Use what we have learned thus far and algebra. 3. Convert to sines and cosines. If stuck, this can be helpful.

  5. Proving Trig. Identities Ex: Verify the identity Ex: Verify the identity Ex: Verify the identity

  6. Proving Trig. Identities Ex: Verify the identity
