What is The Area of The Largest Rectangle That Can be Inscribed in The Ellipse 4x^2+9y^2=36
Calculating the Length of Major and Minor Axes
To determine the area of the largest rectangle that can be inscribed in the ellipse 4x^2 + 9y^2 = 36, we first need to calculate the lengths of its major and minor axes. In an ellipse, the major axis represents the longest distance across while the minor axis corresponds to the shorter distance.
The equation for our given ellipse is in standard form: 4x^2 + 9y^2 = 36. By comparing this equation with the general equation for an ellipse (a^2x^2 + b^2y^2 = c), we can identify that a = √(c/4) and b = √(c/9). Here, c represents the constant term on the right side of our equation (which is equal to 36).
Using these formulas, we find that a = √(36/4) = √9 = 3 and b = √(36/9) = √4 = 2. Therefore, our major axis has a length of 6 units (twice a) and our minor axis has a length of 4 units (twice b).
Determining the Center Point of the Ellipse
Next, let’s determine the center point of our ellipse. In any ellipse given by an equation in standard form, shifting it horizontally or vertically will not change its shape but only its position on a coordinate plane.
For our ellipse with equation 4x^2 + 9y^2 = 36, we notice that there are no terms involving x or y squared alone; they are always multiplied by their respective coefficients. This implies that both x and y are squared terms and thus, the center of our ellipse is at the origin (0, 0).
Calculating the Length of Major Axis
To determine the length of the major axis for the ellipse 4x^2+9y^2=36, we need to find the distance between two farthest points on the ellipse along its horizontal direction. Here’s how we can calculate it:
- Begin by rewriting the equation of the ellipse in standard form: (x^2)/(3^2) + (y^2)/(2^2) = 1. This allows us to identify that a = 3 and b = 2, where a represents half of the length of the major axis and b represents half of the length of the minor axis.
Note: The standard form helps us understand how a and b relate to our original equation. - The length of the major axis (or twice “a”) can be calculated as:
Major Axis Length = 2 * a
In this case, Major Axis Length = 6 units.
And there you have it! The length of the major axis for this particular ellipse is 6 units. Understanding this value will aid us in further calculations related to inscribing rectangles within this elliptical shape.
