Chapter 7: Q. 91 (page 465)

In Problems 81–92, use a graphing utility to solve each equation. Express the solution(s) rounded to two decimal places.
$6 \sin x - e^{x} = 2, x > 0$

Short Answer

Expert verified

The solution set is $\{0.76, 1.35\}$

Step by step solution

Step 1. Given Information

In the given problems we have to use a graphing utility to solve each equation and express the solution(s) rounded to two decimal places.

$6 \sin x - e^{x} = 2, x > 0$

Step 2. This type of trigonometric equation cannot be solved by previous methods. A graphing utility, though, can be used here.

Each solution of this equation is the x-coordinate of a point of intersection of the graphs of $Y_{1} = 6 \sin x - e^{x} and Y_{2} = 2$ .

Step 3. The graph of the given equation is

Step 4. There are three points of intersection; the x-coordinates are the solutions that we seek.

Using INTERSECT, we find

$x = 0.76 x = 1.35$

The solution set is $\{0.76, 1.35\}$
