Radian Measure 3 Degree Measure 4 Periodic Functions 5 Trigonometric Functions 6 Elementary Trigonometric Identities 7 Values of Trigonometric Functions 8 Special Angles 9 Example: Finding Trigonometric Function Values of a Quadrant Angle ● ● Find the values of the trigonometric functions for 210°. Reference angle: 210° – 180° = 30° Choose point P on the terminal side of the angle so the distance from the origin to P is 2.

The function x2 4 f ( x) x2 is not defined at x = 2, so its graph has a “hole” at x = 2. Values of f(x) may be computed near x = 2 Determining the Limit from the Graph of the Function Determining Whether a Limit Exists One-Sided Limits One-Sided Limits Example:One-Sided Limits 3.4 Definition of the Derivative Copyright © 2008 Pearson Education, Inc. 30 31 Chapter 4 Calculating the Derivative Copyright © 2008 Pearson Education, Inc. 4.1 Techniques for Finding Derivatives Copyright © 2008 Pearson Education, Inc. 34 35
