Chapter 6 - 6.6 - Inverse Trigonometric Functions - 6.6 Exercises - Page 484: 31

$$42.6\ degrees$$

Work Step by Step

We are asked to use a calculator to evaluate each of the following expressions. Thus, as the book mentions on pages 480 and 481, it is important to note that $arcsin$ is the same as $sin^{-1}$, $arccos$ is the same as $cos^{-1}$, and $arctan$ is the same as $tan^{-1}$. Knowing this, we plug the value into the calculator to find the answer is: $$42.6\ degrees$$
