Attachments: File | Description | File size | | | 2381 kB | 12.4.1b Coterminal AnglesAngles in standard position use the positive side of the x-axis as the inital arm. Counter-clockwise rotations from this initial arm produce positive angles, and clockwise rotations produce negative angles. Sometimes, different angles can end up with the same terminal arm. These are called coterminal angles. Assignment: Things you should know how to do after today: - define an angle in standard position

Trigonometry (Algebra 2 Curriculum - Unit 12) | All Things Algebra®What educators are sayingAlso included in. DescriptionDue to the length of this Trigonometry Unit Bundle , it is divided into two parts with two unit tests. In addition to the unit tests, each part includes guided notes, homework assignments, quizzes, and study guides to cover the following topics: Unit 12 Part I: • Pythagorean Theorem • Special Right Triangles • Trigonometric Functions (sin, cos, tan, csc, sec, cot) • Finding Side and Angle Measures • Applications: Angle of Elevation and Depression • Angles in Standard Position • Converting between Degrees and Radians • Coterminal and Reference Angles • Trigonometric Functions in the Coordinate Plane • The Unit Circle • Law of Sines • Law of Cosines • Area of Triangles • Applications of Law of Sines, Law of Cosines, and Area Unit 12 Part II: • Graphing Trigonometric Functions • Trigonometric Identities • Sum and Difference of Angle Identities • Double-Angle and Half-Angle Identities • Solving Trigonometric Equations ADDITIONAL COMPONENTS INCLUDED: (1) Links to Instructional Videos: Links to videos of each lesson in the unit are included. Videos were created by fellow teachers for their students using the guided notes and shared in March 2020 when schools closed with no notice. Please watch through first before sharing with your students. Many teachers still use these in emergency substitute situations. (2) Editable Assessments: Editable versions of each quiz and the unit test are included. PowerPoint is required to edit these files. Individual problems can be changed to create multiple versions of the assessment. The layout of the assessment itself is not editable. If your Equation Editor is incompatible with mine (I use MathType), simply delete my equation and insert your own. (3) Google Slides Version of the PDF: The second page of the Video links document contains a link to a Google Slides version of the PDF. Each page is set to the background in Google Slides. There are no text boxes; this is the PDF in Google Slides. I am unable to do text boxes at this time but hope this saves you a step if you wish to use it in Slides instead!

Unit 12 - Statistics. The field of statistics is rich with details and theory that cannot even begin to be touched in this unit. A true study of statistics and the interpretation and comparison of data sets truly needs deeper treatment than what is given in this time-limited course. This unit begins by introducing sigma notation.
In this course students will learn about a variety of advanced topics in algebra. Students will expand their understanding about functions by learning about polynomial, logarithmic, and trigonometric functions. These new functions along with linear, quadratic, and exponential, will be used to model a variety of problems, including compound interest, complex numbers, growth and decay ...
