Trigonometry is essentially
the study of how lengths vary compared to the rotations or angles that create the length. Thus, this unit begins with
careful development of essential angle and rotation terminology, including reference angles, quadrant work, and radian angle
measurement. The sine and cosine functions are then defined in terms of the unit circle. Graphs of sine and cosine
are developed from the simple to the complex. Important terminology, such as amplitude, frequency, period, and midline
are reinforced through real world applications. The four trigonometric ratio functions are then defined with their basic
characteristic and graphs examined.
