Q. Write an equation for an ellipse centered at the origin, which has foci at (±13,0) and co-vertices at (0,±11).
Identify Orientation: We have:Foci: (±13,0)Co-vertices: (0,±11)Choose the orientation of the ellipse.Since the foci are on the x-axis, the ellipse is horizontal.
Identify Center and Foci: We have:Center (h,k): (0,0)Foci: (±13,0)Identify the value of c.c=13
Identify Co-vertices: We have:Center (h,k): (0,0)Co-vertices: (0,±11)Identify the value of b.b=11
Calculate Value of a: We know the relationship between a, b, and c in an ellipse is c2=a2−b2. We already have c=13 and b=11. Calculate the value of a. a2=c2+b2a2=(13)2+112a2=13+121b0b1
Standard Form of Ellipse: We know:(h,k)=(0,0)a=134b=11What would be the standard form of the ellipse?a2(x−h)2+b2(y−k)2=1(134)2(x−0)2+112(y−0)2=1134x2+121y2=1
