CR00733 - Trigonometry 02103

In this one-semester course, students use their geometry and algebra skills to begin their study of trigonometry. Students will be required to express understanding using qualitative, quantitative, algebraic, and graphing skills. This course begins with a quick overview of right-triangle relationships before introducing trigonometric functions and their applications. Students explore angles and radian measures, circular trigonometry, and the unit circle. Students extend their understanding to trigonometric graphs, including the effects of translations and the inverses of trigonometric functions. This leads to the laws of sines and cosines, followed by an in-depth exploration of trigonometric identities and applications. This course ends with an introduction to the polar coordinate system, complex numbers, and DeMoivre’s theorem. The online course also includes audio resources that can "read" content to students along with 18 different language translation options. Students will take a diagnostic pre-assessment prior to beginning each lesson and do not need to re-take those lessons where they demonstrate the ability to meet standards. This course is offered as a credit recovery option with teachers located in South Dakota.
