學習目標
- Define trig functions for negative angles and angles greater than 90 degrees.
- Translate between multiple representations of trig functions: as sides of a right triangle inscribed in a unit circle, graph of the function vs. angle, and numerical values of the function.
- Deduce the sign (+, -, 0) of a trig function for any given angle without a calculator using the unit circle concept.
- Estimate the value of trig functions for any given angle without a calculator using the unit circle concept.
- Define exact trig functions for special angles using degrees or radians for angle measures.
