Lesson Plan Graphing Sine and Co repulsivenesse Lynn Weiss Goal: Students go out lend sensationself technology to go steady how to represent trigonometric functions. They forget land hand and glove to imitate sine and romaine functions after real worldly concern applications. Prerequi baites: Students should sire a canonical intimacy of the unit roofy. They should experience how to chart y = sin(x) and y = cos(x). They should discover basic trigonometric definitions much(prenominal) as amplitude, period, and shift. Materials: Students should have a TI Graphing information processing system (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 over the graphs of y = sin(x) and y = cos(x). They use butcher paper and spaghetti along with their experience of right trilateral trig and the unit circle to graph the functions. This lesson volition begin on the school solar day avocation the completion of this lab. solar day 1: 1. reassessment graphing y = sin(x) and y = cos(x). Be sure that scholars know the amplitude, period, compass and range of the functions. address how to graph the functions in both radian and degree mode. 2. leave the worksheet Graphing Calculator Exploration, Graphing Sine and Cosine. do students work respectively to fetch up the worksheet.

They should discover how granted the equality y = a sin b(x-c)+ d, changes in a, b, c, and d violence the graph. 3. Go over the answers to the worksheet as a class. Have students offer up to explain their solutions. Day 2 1. acquaint a pop checkmate quiz to value students knowledge of graphing sine and cosine. The quiz lead ask them to graph a function and to determine the equality of a given graph. 2. diffuse index cards to every students in the class. from each one classroom table will have a class with an answer on it. The students will use their knowledge of the unit circle to find other 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 furbish up a rich essay, order it on our website: Ordercustompaper.com
