(b)
To find: The points of intersection of the functions
(b)
Answer to Problem 35E
The points of intersection of the functions
Explanation of Solution
Given information:
The functions are
Calculation:
To get the intersection points of both the functions equate both the functions.
As cosine has period
Therefore, the solution to the equation in
As cosine repeats its values after every
So, the general solution of the equation is given by
Now calculate the function value at each point of intersection.
Therefore, The points of intersection of both the graphs are
