To find:
The functionof period and graph of the function

Answer to Problem 9E
The functions tangent have period
Explanation of Solution
Given:
The function is
Concept used:
The functions tangent and cotangent have period
The functions cosecant and secant have period
Calculation:
The function is
Since the tangent and cotangent function have period
The function
Complete one period as
That is for
Solving this inequality
So each period is
The functions tangent have period
Draw the graph of the function
Draw the table
Test one point in each of the region formed by the graph
If the point satisfies the function then shade the entire region to denote that every point in the region satisfies the function
