Unformatted text preview: 2.7 Graphs of Secant and Cosecant Functions Part 2 Tuesday, September 27, 2011 7:38 AM Please check the "No-Name" wall for any of your work! Agenda: 1. Classwork 2. Lesson: 2.7 Graphs of Secant and Cosecant Functions Part 2 ________________________________ Whiteboard Work Find the measure of each angle , Questions to ask (and answer) • What quadrant(s) does live in? • What is the measure of '? ________________________________ Lesson: 2.7 Graphs of Secant and Cosecant Functions Goal: Graph Secant and Cosecant Functions DOD For Vertical stretch/shrink: period: and , horizontal shift: vertical shift: There is a relationship between Sine and its reciprocal, Cosecant. There is a relationship between Cosine and its reciprocal, Secant. • We will use Sine or Cosine graphs to help us graph Cosecant and Secant graphs! Let me show you… Ch_2 Page 1 ________________________________ Argh! I messed up… let me tell you how… Horizontal shifts (with ) Factor first! Then you can see the horizontal shifts... Examples State the period, phase shift, and vertical shift of the graph. ________________________________ Examples State the period, phase shift, and vertical shift of the graph. Then graph the function. To graph, we will first graph its corresponding Sine or Cosine function. So graph first! Ch_2 Page 2 So graph first! You try one! (Whiteboard) Ch_2 Page 3 Ch_2 Page 4 ...
