If  touches The Ellipse , Then Its Eccentricity Angle θ Is Equal To

The eccentricity of the ellipse which meets the straight line  on the axis of x and the straight line  on the axis of y and whose axes lies along the axes of coordinates is

The line lx + my + n = 0 is a normal to the ellipse  if

If the normal at any point P on the ellipse cuts the major and minor axes in G and g respectively and C be the center of the ellipse

The angle between the pair of tangents drawn from the point (1, 2) to the ellipse 3x² + 2y² = 5 is

The ellipse  cuts x-axis at A and A’ and y-axis at Band B’. The line joining the focus S and B makes an angle  with x-axis. The eccentricity of the ellipse is

A circle is drawn on the major axis of the ellipse 9x² + 16y² = 144 as diameter. The equation of circle is

The equation  represents an ellipse, if

S and T are the foci of an ellipse and B is an end of the minor axis. If STB is an equilateral triangle, the eccentricity of the ellipse is 

The locus of mid-points of focal chords of the ellipse  is 

If the polar with respect to the parabola y² = 4ax touches the ellipse , then the locus of its pole is
