Lesson Plan: Signs of Trigonometric Functions in Quadrants Mathematics
This lesson plan includes the objectives of the lesson teaching students how to identify in which quadrant an angle lies and whether its sine, cosine, and tangent are positive or negative.
Objectives
Students will be able to
- identify the quadrant a given angle lies in,
- identify which quadrant an angle lies in given information about a trigonometric evaluation of that angle,
- determine the sign of a numerical trigonometric expression.
