Trigonometry is a field of mathematics in which the geometric properties of the angles and edges of triangles are examined in detail. Real-world problems involving trigonometry are common in engineering, physics, construction and design.

For students who are proficient in College algebra, this course presents trigonometric functions, polar functions, trigonometric equations, and solutions of right triangles and oblique triangles. Polar coordinates, complex numbers, parametric equations, and vectors are also introduced. Students are required to learn basic trigonometric facts such as the sine, cosine, and tangent values of special angles without using a calculator. Students are also required to learn the fundamental trigonometric identities.

Upon completion of this course students will be able to
