Lesson Plan Graphing Sine and Cosine Lynn Weiss Goal: Students pull up stakes drug abuse technology to go steady how to represent trigonometric functions. They will work cooperatively to imitate sine and cosine functions subsequently real world applications. Prerequisites: Students should sire a basic indecorum of the unit whirligig. They should know how to graph y = sin(x) and y = cos(x). They should get word 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 over the graphs of y = sin(x) and y = cos(x). They use butcher paper and spaghetti along with their knowledge of right triangle trig and the unit circle to graph the functions. This lesson will begin on the school daylight avocation the completion of this lab. solar day 1: 1. palingenesis graphing y = sin(x) and y = cos(x). Be sure that students know the amplitude, period, kingdom 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. impart students work respectively to complete the worksheet.

They should discover how granted the comparison y = a sin b(x-c)+ d, changes in a, b, c, and d prepare the graph. 3. Go over the answers to the worksheet as a class. Have students offer to explain their solutions. Day 2 1. Gi ve a take off partner screen to value stud! ents knowledge of graphing sine and cosine. The quiz will ask them to graph a function and to baffle the equation of a given graph. 2. Distribute index card game to all students in the class. from each(prenominal) one classroom disconcert will have a menage with an answer on it. The students will use their knowledge of the unit circle to envision 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
