Teaching OSSSC TGT Teachers Mock Test Series 2025 Mathematics Parabola, Ellipse and Hyperbola Ellipse
The eccentricity of an ellipse centered at the origin is 1/4. If one of its directrices is x = -8, then the equation of the normal to it at (3, -5) is:
1
20x + 9y = 15
2
-20y - 9x = 15
3
9x - 20y = 15
4
-9x + 20y = 15
