Q. Write an equation for an ellipse centered at the origin, which has foci at (±12,0) and vertices at (±37,0).
Given Information: We are given:Foci: (±12,0)Vertices: (±37,0)Since the vertices and foci are on the x-axis, this indicates a horizontal orientation for the ellipse.The distance from the center to a vertex is ′a′, and the distance from the center to a focus is ′c′.We can determine the values of ′a′ and ′c′ from the given information.a=37c=12
Find 'b': Next, we need to find the value of 'b', which is the distance from the center to the co-vertices. The relationship between 'a', 'b', and 'c' for an ellipse is given by the equation c2=a2−b2. We can rearrange this to solve for 'b': b2=a2−c2
Calculate 'b': Now we will plug in the values of 'a' and 'c' to find 'b':b2=(37)2−(12)2b2=37−12b2=25Taking the square root of both sides, we get:b=25b=5
Standard Form Equation: With the values of a and b, we can now write the equation of the ellipse in standard form. For a horizontal ellipse centered at the origin, the standard form is: a2x2+b2y2=1
Substitute Values: Substituting the values of a and b into the standard form equation, we get: (372x2)+(52y2)=1 Simplifying the equation, we have: (37x2)+(25y2)=1
