MA 106 – Precalculus: Trigonometry
Fall 2026 Course Page
Description
This course develops the trigonometric functions and their use in solving problems: angles and radian measure, right-triangle trigonometry, the unit circle, graphs of the trigonometric functions, inverse trigonometric functions, identities, trigonometric equations, and applications such as the Laws of Sines and Cosines.
Many topics begin with a short inquiry-based activity, in which students explore a pattern in small groups before the method is formally introduced.
