8 Trigonometric Functions of Any Angle


After completion of this chapter, the student should be able to:

  • Determine the magnitude and sign of any trigonometric function of any angle

  • Identify reference angles and use them to evaluate trigonometric functions of angles in any quadrant

  • Express an angle in degrees or radians and convert between the two measurements

  • Given the value of a trigonometric function of an angle, find the angle(s)

  • Use radian measure of an angle to find circular arc length

  • Solve problems involving area of a sector of a circle

  • Solve problems involving angular velocity

  • Solve application problems involving trigonometric functions of any angle

When we introduced the trigonometric functions in Chapter 4, we ...
