WebMay 9, 2024 · We know that the vertices and foci are related by the equation c2 = a2 − b2 . Solving for b2, we have: c2 = a2 − b2 25 = 64 − b2 Substitute for c2 and a2 b2 = 39 Solve for b2. Now we need only substitute a2 = 64 and b2 = 39 into the standard form of the equation. The equation of the ellipse is x2 64 + y2 39 = 1. WebDec 8, 2024 · Figure 8: Horizontal ellipse centered out of the origin. The equation that defines an ellipse of the type shown in Figure 8 is: (x−h)2 a2 + (y−k)2 b2 =1 ( x − h) 2 a 2 + ( y − k) 2 b 2 = 1 ...
