  4. What is an Identity? An identity is a statement that two expressions are equal for every value of the variable. Example: www.mccd.edu/.../PowerPoints/Verifying%20Trigonometric%20Iden...

  5. Quotient Identities The Fundamental Identities Reciprocal Identities The beauty of the identities is that we can get all functions in terms of sine and cosine. www.mccd.edu/.../PowerPoints/Verifying%20Trigonometric%20Iden...

  6. Identities for Negatives The Fundamental Identities www.mccd.edu/.../PowerPoints/Verifying%20Trigonometric%20Iden...

  7. The Fundamental Identities Pythagorean Identities X The only unique Identity here is the top one, the other two can be obtained using the top identity… www.mccd.edu/.../PowerPoints/Verifying%20Trigonometric%20Iden...

  8. Divide all terms by cos2 cos2 cos2 cos2 What trig function is this squared? 1 What trig function is this squared? Divide all terms by sin2 sin2 sin2 sin2 1 What trig function is this squared? What trig function is this squared? www.gdn.edu/faculty/mzabdawi/Pre-Calculus/Sec%206.2.ppt

  9. Variations of these Identities Variations of Identities using Arithmetic We can create different versions of many of these identities by using arithmetic. www.mccd.edu/.../PowerPoints/Verifying%20Trigonometric%20Iden...
