To calculate: The slope of the curve at each indicated point.
Answer to Problem 39E
The required slope is 1.
Explanation of Solution
Given information:
The curve:
The point:
Calculation:
The given curve is
It is known that in a polar
Rewrite x and y as:
And,
Since, polar curves lie in xy -plane; so, the slope of the polar curve and the slope of the tangent are same that is,
The slope can be written as:
Now, substitute 0 for
Hence, the required slope is 1.
