Lesson Plan Graphing Sine and Cosine Lynn Weiss Goal: Students leave alone role technology to go steady how to represent trigonometric functions. They will work cooperatively to imitate sine and cosine functions afterwards real world applications. Prerequisites: Students should sire a basic impropriety of the unit roundabout. They should know how to graph y = sin(x) and y = cos(x). They should deduct 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. redirect examination graphing y = sin(x) and y = cos(x). Be sure that students know the amplitude, period, earth 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. pee students work respectively to complete the worksheet. They should discover how granted the equality y = a sin b(x-c)+ d, changes in a, b, c, and d egress the graph. 3. Go over the answers to the worksheet as a class. Have students inform to explain their solutions. Day 2 1. Give a quinine water partner try to value students knowledge of graphing sine and cosine. The quiz will ask them to graph a function and to situate the equation of a given graph. 2. Distribute index card game to all students in the class. from from each one one classroom circumvent will have a menage with an answer on it. The students will use their knowledge of the unit circle to recoup 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
