Q. Write an equation for an ellipse centered at the origin, which has foci at (0,±6) and vertices at (0,±10).
Given Information: We are given:Foci: (0,±6)Vertices: (0,±10)Since the vertices and foci are on the y-axis, this indicates a vertical orientation for the ellipse.
Center of the Ellipse: The center (h,k) of the ellipse is at the origin, so h=0 and k=0.
Value of 'a': The distance from the center to a vertex is the value of 'a'. Since the vertices are at (0,±10), we have:a=10
Value of 'c': The distance from the center to a focus is the value of 'c'. Since the foci are at (0,±6), we have:c=6
Calculation of 'b': We need to find the value of 'b'. The relationship between a, b, and c for an ellipse is c2=a2−b2. We can solve for b2: b2=a2−c2 b2=102−62 b2=100−36 b2=64
Value of 'b': Now we can find the value of 'b':b=b2b=64b=8
Equation of the Ellipse: We can now write the equation of the ellipse in standard form. Since the ellipse is vertically oriented, the equation is:(x−h)2/b2+(y−k)2/a2=1Substituting the values of h, k, a, and b, we get:(x−0)2/82+(y−0)2/102=1x2/64+y2/100=1
