Trigonometry (13 Lessons) (13 lessons, $33.66)
This 73 minute trigonometry lesson covers angles in standard position, coterminal 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 coterminal 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.
Lessons that will help you with the fundamentals of this lesson include:
