Trigonometry

Course Overview

In Trigonometry, students learn about the relationships between the sides and the angles of triangles and how to make calculations based on them using trigonometric functions.  Courses include:

• similarity and proportion, 30-60-90 and 45-45-90 right triangles, rationalizing the denominator, degrees, minutes, and seconds.
• sine, cosine and tangent, word problems for each, as well as Pythagorean and tangent identities.
• radians and special angles, arc length, sector area, extended angles – coterminal, unit circle, and new definitions.
• reciprocal and inverse functions
• areas of triangles and the laws of sines and cosines
• magnitude and directions, horizontal and vertical components, adding vectors geometrically and algebraically, and compass headings.
• cofunction and negative angle identities, and simplifying expressions.
• combining like terms, square roots, factoring, and quadratics.
• problem-solving in trigonometry
