Trig: Trigonometry on the Coordinate Plane - 320

This lesson is part of the series: Trigonometry

This 73 minute trigonometry lesson covers angles in standard position, co-terminal angles and principal angles. The six trig ratios are defined for an angle in standard position and the CAST rule is introduced. The lesson finishes with finding reference angles. This lesson will show you how to :
- draw positive and negative angles in standard position
- find positive and negative angles co-terminal with a given angle
- find the principal angle
- work with the terminal arm, positive and negative angles,
- find the six trig ratios of an angle in standard position in all four quadrants
- use and understand the CAST rule
- find reference angles
- work with quadrantal angles

This lesson contains explanations of the concepts and 15 example questions with step by step solutions plus 5 interactive review questions with solutions.
