Radian Measurement
The discovery approach is used to examine an angle of one radian. Introduces the concept of radian measure and shows how to convert from radians to degrees and vice versa. Applications of radian measure to arc length and angular velocity are explained.
-
Development of Circular Functions
Reviews previously learned vocabulary and concepts of the primary trigonometric ratios, degree/radian relationship and the development and application of special, quadrantal, reference and coterminal angles.
-
Applications of Circular Functions
Students learn how to solve trigonometric equations of primary or reciprocal functions either algebraically or graphically.
-
Graphing Trigonometric Functions
Students explore the relationship between radians and degrees and learn how to graph primary and reciprocal functions. Emphasis is placed on the importance of understanding the function’s properties including domain, range, period, and y-intercepts.
-
Investigating the Properties of a,b,c and d
Using computer technology, students investigate the transformations of the trigonometric functions y = asin[b( c)]+d and y = acos[b( c)]+d.
-
Combined Transformations of Trigonometric Functions
Demonstrates different methods of graphing transformations of trigonometric functions.
