Lesson: 2.2 Cofunctions, Odd and Even Functions ____________________________ Classwork ____________________________ Lesson: 2.2 Cofunctions, Odd and Even Trig Functions Goal: Use properties of trig functions to evaluate trig functions. DOD Two angles are complementary if the sum of their measures are What angle is complementary to What angle is complementary to What angle is complementary to . ? ? Do some evaluations for me. If , then If , then If , then You have just shown the property that cofunctions of complementary angles are equal! Cofunctions Sine and Cosine Tangent and Cotangent Secant and Cosecant Ch_2 Page 1 Sine and Cosine Tangent and Cotangent Secant and Cosecant Odd and Even Functions Remember…. Odd Function Even Function Let's do some evaluations… Odd Trig Functions Even Trig Functions ______________________________ Examples Use the fact that trig functions are odd or even, periodic, and the property of cofunctions to evaluate.
