Q. Write an equation for an ellipse centered at the origin, which has foci at (±5,0) and vertices at (±41,0).
Given Data: We are given the foci at (±5,0) and vertices at (±41,0). Since the foci and vertices are on the x-axis, this indicates a horizontal orientation for the ellipse.
Calculate a: The distance from the center to a vertex is represented by a, and the distance from the center to a focus is represented by c. Using the given vertices, we can find the value of a.a=41
Calculate 'c': Using the given foci, we can find the value of 'c'.c=5
Use Relationship Equation: The relationship between a, b, and c for an ellipse is given by the equation c2=a2−b2. We can use this to find the value of b. c2=a2−b2 52=(41)2−b2 25=41−b2 b2=41−25 b2=16
Find 'b': Now we can find the value of 'b' by taking the square root of b2.b=16b=4
Write Standard Form: With the values of a and b, we can write the standard form equation of the ellipse. Since the ellipse is horizontally oriented and centered at the origin, the standard form is:(a2x2)+(b2y2)=1
Substitute Values: Substitute the values of a and b into the equation.(412x2)+(42y2)=1(41x2)+(16y2)=1
