Use a graph of the function to approximate the solution of the equation on the interval

[−2π, 2π].
(List the solutions in increasing order from left to right on the x-axis. Round your answers to three decimal places.)

To approximate the solution of an equation on a given interval using a graph, follow these steps:

1. Plot the graph of the given function on the interval [-2π, 2π]. Make sure to label the x-axis and y-axis with appropriate values.

2. Identify the x-values where the graph intersects the x-axis. These points represent the solutions of the equation.

3. Locate the x-intercepts on the graph and read the x-values from left to right on the x-axis.

4. Round the x-values to three decimal places to approximate the solutions.

Please provide the equation or the graph of the function, and I will help you with the specific solutions.
