To find: The points of horizontal.
Answer to Problem 25E
The answer:
Explanation of Solution
Given information:
The equations are:
Calculation:
Since need to find the points at which the tangent line to the curve is horizontal, need to find the relative extrema of the function
Know that function
So,
To use the previous result,
Then,
For
has the relative extrema at points
In this exercise,
Then,
which means that the points at which the tangent line to the curve is horizontal are equal to
Therefore, the required horizontal points are
To find: The points of vertical.
Answer to Problem 25E
The answer: Does not exists.
Explanation of Solution
Given information:
The equations are:
Calculation:
Since need to find the points at which the tangent line to the curve is vertical, need to find the relative extrema of the function
Know that function
So,
To use the previous result,
which means that the function
Therefore, the required vertical points does not exists.
