Pre-Calculus: Trigonometry

Enrollment Message

Students need a scientific calculator is all that is needed for this class. You can use a TI-84, TI-83, or TI-Nspire Calculator. Please note that a TI-89, and TI-Nspire CAS will not be allowed on the Final Exam.

Course Description

Trigonometry is the study of side and angle relationships in triangles and their applications as well as the properties of trigonometric functions. Memorization of the common values of the trigonometric ratios on the unit circle provides a strong foundation for the rest of the course. Trigonometry in right triangles is studied initially and extended into non-right triangles using the Law of Sines and Law of Cosines. Graphs of trigonometric functions are explored including applications. Trigonometric identities are verified and used to solve equations. The concept of polar coordinates is introduced and applied to the topic of complex numbers.

• Fulfills a Mathematics course requirement for all diplomas

Course Goals

Upon completion of the course, students will…

• convert angles from radians to degrees and vice versa.
• evaluate the sine, cosine, tangent, cotangent, secant, and cosecant of angles.
• solve trigonometric equations.
• utilize basic trigonometric identities to manipulate trigonometric expressions.
• recognize and construct graphs of trigonometric function.
• convert points and equations from the rectangular coordinate system to the polar coordinate system.
• use the law of sines and cosines to solve problems.
• find the inverse of an appropriately-restricted sine, cosine, and tangent.

Grading/Evaluation

Indiana Online does not assign letter grades, grant credit for courses, nor issue transcripts or diplomas. A final score reported as a percentage of total points earned will be sent to students upon completion of a course. Your school of record can also access this score within the Student Information System, Genius. The final score will be shown as a percentage in Canvas and Genius. The student’s school of record will determine the letter grade based on their specific grading scale.

Students must complete at least 70% of the course and take all parts of the final exam(s) to have a score reported to their school of record. Failure to meet these requirements will result in a score of 0 reported to the school of record.

Assessments

Online assessments consist of formative and summative assessments represented by computer-graded multiple choice, teacher-graded writing assignments including hands-on projects, model building and other forms of authentic assessments. The course includes the following assessments

• 4 Assignments
• 32 Quizzes

The assessments for this asynchronous course are weighted as follows

Teacher Contact Response Time

Students can use email or the private message system within Genius or Canvas to access highly qualified teachers when they need teacher assistance. Students will also receive feedback on their work inside Canvas. The Teacher Information page of their course may describe additional communication options.

The teacher will respond to student inquiries (email, text, call) within one business day. Assignments will be graded and posted within two business days.
