Objectives. Find sin (-5. ). Find the values of . ϴ. for which . cos. . ϴ. =1 is true.. Graph the function y = sin x for the interval .  . Lesson 6-4 Amplitude and Period of Sine and Cosine Functions. Objective: To find the amplitude and period of sine and cosine functions.. Chapter 3.5. Proving that .  . In section 2.1 you used a table of values approaching 0 from the left and right that . ; but that was not a proof. Because you will need to know this limit (and a related one for cosine), we will begin this section by proving this through geometry. The lessons took a lot longer than anticipated due to gap filling and teaching similarity before this started. Feedback and assessment from students was positive. They said they never understood what sin, cos and tan represented (‘it was a button on the calculator that worked . Here we show three triangles. Each one is a right triangle, and each one contains a 30° angle.. 4 120 240. 2 60 120. And Visa Versa. . Suppose: v. 1. (t) = 1V sin (. w. t). . v. 2. (t) = 1V . cos. (. w. t). The sine wave reaches its maximum when . w. t = 90. o. , but the cosine reaches its maximum when . w. t = 0.
