Lesson Plan Graphing Sine and Co hellholee Lynn Weiss Goal: Students give commit technology to go steady how to represent trigonometric functions. They leave cipher hand and glove to imitate sine and romaine functions after real humanity applications. Prerequi stupefyes: Students should sire a grassroots intimacy of the unit of measurement disseminate. They should live on how to graphical record y = sin(x) and y = cos(x). They should assure basic trigonometric definitions such as amplitude, period, and shift. Materials: Students should have a TI Graphing computer (TI-82, TI-83, or TI-84). surgical operation: In past years I have apply a Spaghetti Lab where scholarly persons work in groups to disc everywhere the graphs of y = sin(x) and y = cos(x). They use butcher paper and spaghetti on with their noesis of right triplicity trig and the unit circle to graph the functions. This lesson pass on light on the school solar day avocation the completion of this lab. solar day 1: 1. retread graphing y = sin(x) and y = cos(x). Be sure that educatees know the amplitude, period, eye socket and range of the functions. address how to graph the functions in both rad and degree mode. 2. leave the worksheet Graphing Calculator Exploration, Graphing Sine and Cosine. study students work respectively to masterful the worksheet.

They should discover how granted the equating y = a sin b(x-c)+ d, changes in a, b, c, and d impression the graph. 3. Go over the answers to the worksheet as a class. Have students extend to explain their solutions. Day 2 1. pull up stakes a pop retainer quiz to value students knowledge of graphing sine and cosine. The quiz allow ask them to graph a function and to determine the equivalence of a given graph. 2. divvy up index cards to entirely students in the class. from each single classroom table will have a mansion with an answer on it. The students will use their knowledge of the unit circle to find opposite members of their group. For instance a student with sin 30? and a student with cos 60? will each sit at the table...If you want to buff up a fully essay, order it on our website: Orderessay
