The purpose of this Geogebra Book is to accompany Unit 6 of the Algebra 2 Illustrative Mathematics curriculum. The activities are not intended to entirely replace Unit 6, but instead to supplement/replace certain activities within the unit. It is intended to be a resource for teachers who can assign activities at specific times within lessons or the unit (see "Sequence" column below).[br][br][br][table][tr][td]Activity[/td][td]Learning Targets[/td][td]Sequence[/td][/tr][tr][td]Measuring Circles Using the Radius[br]2.6.3[/td][td][list][*]I understand that a radian angle measurement is the ratio of the arc length to the radius of the circle.[/*][/list][/td][td]In place of Activity #3 in Lesson #3[br](2.6.3.3)[/td][/tr][tr][td]Pythagorean Identity[br]2.6.5[/td][td][list][*]I understand that cosine and sine are defined as the x- and y-coordinates of a point on the unit circe at [math]\theta[/math] radians.[/*][/list][/td][td]In place of Lesson #5[br](2.6.5)[/td][/tr][tr][td]Introduction to Trigonometric Functions[br]2.6.9[/td][td][list][*]I can use the coordinates of points on the unit circle to graph the cosine and sine functions.[/*][/list][/td][td]In place of Lesson #9[br](2.6.9)[/td][/tr][tr][td]Beyond [math]2\pi[/math][br]2.6.10[/td][td][list][*]I understand how to find the values of cosine and sine for inputs greater than [math]2\pi[/math] radians.[/*][/list][/td][td]In place of Lesson #10[br](2.6.10)[/td][/tr][tr][td]Amplitude and Midline[br]2.6.13[/td][td][list][*]I can write a trigonometric function to represent situations with different amplitudes and midlines.[/*][/list][/td][td]In place of Activities #2&3 in Lesson 13[br](2.6.13.2-1.6.13.3)[/td][/tr][tr][td]Modeling Circular Motion[br]2.6.18[/td][td][list][*]I can represent a circular motion situation using a graph and an equation[/*][/list][/td][td]In place of Activities #1&2 in Lesson 18[br](2.6.18.1-2.6.18.2)[/td][/tr][/table]
