(a)
To find: TheGraphing device to graph the function.
(a)
Answer to Problem 57RE
The function
The graph is increase with increase in the value of angle.
Graph is like a
Explanation of Solution
Given:
Concept used:
Modulus function make the graph shifted in the region of positive.
Its
Calculation:
Graph of the
Graphing device use here is Desmos graphing calculator. from the graph modulus symbolize the positivity of the function which is shown in the graph and the
Through graph range can determined which is
Hence the function
(b)
To find:whether the Function is periodic if then described it.
(b)
Answer to Problem 57RE
The function is not periodic in nature.
Explanation of Solution
Given:
Concept used:
Period is measured as distance it takes for the entire graph to repeat.
Since the period of the Cosine function is
Calculation:
Form the graph its clearly verified the periods as:
the entire graph doesn’t repeat so its not he periodic function.
It’s varies with varies in the value of angle.
Hence the function is not periodic in nature.
(c)
To find: The graph whether the function is even or odd.
(c)
Answer to Problem 57RE
The given function is even.
Explanation of Solution
Given:
Concept used:
Calculation:
Since
Even function when multiply by the even function then whole composite function becomes even function.
Hence the given function is even.
