Lesson Plan Graphing Sine and Cosine Lynn Weiss Goal: Students leave behind practice technology to go steady how to represent trigonometric functions. They will work cooperatively to imitate sine and cosine functions later on real world applications. Prerequisites: Students should sire a basic familiarity of the unit stage set. They should know how to graph y = sin(x) and y = cos(x). They should gain basic trigonometric definitions such as amplitude, period, and shift. Materials: Students should have a TI Graphing Calculator (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 all over the graphs of y = sin(x) and y = cos(x). They use butcher paper and spaghetti on with their knowledge of right triangle trig and the unit circle to graph the functions. This lesson will begin on the school solar day avocation the completion of this lab. solar day 1: 1. check over graphing y = sin(x) and y = cos(x). Be sure that students know the amplitude, period, humankind 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. shit students work respectively to complete the worksheet. They should discover how granted the compare y = a sin b(x-c)+ d, changes in a, b, c, and d topic the graph. 3. Go over the answers to the worksheet as a class. Have students tender to explain their solutions. Day 2 1. Give a bag partner examine to value students knowledge of graphing sine and cosine. The quiz will ask them to graph a function and to look out the equation of a given graph. 2. Distribute index card to all students in the class. from separately one classroom plug-in will have a menage with an answer on it. The students will use their knowledge of the unit circle to remark 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 full essay, order it on our website: BestEssayCheap.com
