Trigonometry Online

Pre-Trigonometry is a five-unit elective course for high school students who have successfully completed Algebra I, Geometry, and Algebra II. The materials cover a development of trigonometry from right triangle trigonometry to oblique triangles and the polar plane. Throughout the course, students will develop trigonometric formulas and use them in real-world applications, evaluate trigonometric proofs using complex trigonometric identities and solving trigonometric equations with regard to the unit circle. Students will study right triangle trigonometry; graphing and inverse functions; analytic trigonometry; trigonometric applications; polar coordinates.

The course seeks to help students expand their knowledge and skills so that they may achieve the following goals: use trigonometry as a tool for indirect measurement; model natural phenomenon with trigonometric functions; perform operations with complex numbers using trigonometry; use trigonometric identities to evaluate trigonometric proofs and solve trigonometric equations with regard to the unit circle; solve for unknown sides and angles of right and oblique triangles using right triangle trigonometry, law of sines and law of cosines.

In attaining these goals, students will begin to see the “big picture” of mathematics and understand how numeric, algebraic, and geometric concepts are woven together to build a foundation for higher mathematical thinking.Calculus prepares students for calculus and college level math with interactive online lessons and advanced problem solving. Students will explore the purpose of calculus and mathematical analysis while they expand their algebraic knowledge through the realm of trigonometry. With a clear, step-by-step delivery, this online course covers a wide range of mathematical concepts including an in-depth observation of math functions, quadratic inequalities, logarithms, probabilities, and permutation. Lessons are interactive to encourage retention of complex information and provide learning tools to clarify complicated mathematic operations.
