  1. 13.4 Inverse Trigonometric FunctionsNotes A Using your calculator, find the values below to the nearest thousandth. (a) sin 130o (b) tan

  2. In the first three sections of this chapter, you learned to evaluate trigonometric functions of a given angle. In this section you will study the reverse problem – finding the angles that correspond to a given value of a trigonometric function. Which angle(s) have a sin of 0.5?

  3. Inverse Trig Functions Inverse sine: Inverse cosine: Inverse tangent:

  4. Example 1: Evaluating Inverse Trig Functions Evaluate each expression in both radians and degrees. sin-1 cos-1 2 tan-1(-1)

  5. Practice:
