(a)
To develop:A formula for the area of an ellipse with equation
(a)
Answer to Problem 50E
Explanation of Solution
Given information: Geometry: The Square has an area of 1 square unit. If the square is stretched horizontally by a factor of a and compressed vertically by a factor of b , the area of the rectangle formed is
Calculation:
Comparing the area of the square
You see you can write the circle as
As you stretch the circle out,
You get instead
(b)
To find:The area of the ellipse
(b)
Answer to Problem 50E
Explanation of Solution
Given information: Geometry: The Square has an area of 1 square unit. If the square is stretched horizontally by a factor of a and compressed vertically by a factor of b , the area of the rectangle formed is
Calculation:
So the area of the ellipse is:
