Question
The function described in Exercise 93, is graphed below in a [0, 50, 10] by [0, 1, 0.1] viewing rectangle. Use the graph to describe what happens to your viewing angle as you move farther back from the screen. How far back from the screen, to the nearest foot, should you sit to maximize your viewing angle? Verify this observation by finding the viewing angle one foot closer to the screen and one foot farther from the screen for this ideal viewing distance.
Solution
The first step in solving 4.7 problem number 94 trying to solve the problem we have to refer to the textbook question: The function described in Exercise 93, is graphed below in a [0, 50, 10] by [0, 1, 0.1] viewing rectangle. Use the graph to describe what happens to your viewing angle as you move farther back from the screen. How far back from the screen, to the nearest foot, should you sit to maximize your viewing angle? Verify this observation by finding the viewing angle one foot closer to the screen and one foot farther from the screen for this ideal viewing distance.
From the textbook chapter Inverse Trigonometric Functions you will find a few key concepts needed to solve this.
