a.
Answer to Problem 103E
Explanation of Solution
Given information:
Use a graphing utility to confirm the solutions found in Example
Graph both sides of the equation and find the
Calculation:
Consider the function,
The graph of the function is as shown,
Hence, the intersection of the graph gives the solution of the equation,
b.

c.
Identify the best method.
c.
Answer to Problem 103E
First method is best.
Explanation of Solution
Given information:
Use a graphing utility to confirm the solutions found in Example
Do both methods produce the same x-values? Which method do you prefer? Explain.
Calculation:
As we observed that both the methods gives the sema solution, we will prefer first metod that it is easier to construct the graph of basic trigonometric functios rather than plotting the whole equation.
Hence, first method is best.
