S is one focus of an ellipse and P is any point on the ellipse. Ifthe maximum and minimum values of SP are m and n respectively, then the length of semi major axis is

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 centre of the ellipse, then

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 centre of the ellipse, then

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 centre of the ellipse, then

If (0, 3+sqrt5) is a point on the ellipse whose foci and (2, 3) and (-2, 3) , then the length of the semi - major axis is

If (0, 3+sqrt5) is a point on the ellipse whose foci and (2, 3) and (-2, 3) , then the length of the semi - major axis is

A focus of an ellipse is at the origin the directrix is the line x=4 and the eccentricity is 1/2 . Then the length of semi major axis is

The foci of an ellipse are located at the points (2,4) and (2,-2) . The point (4,2) lies on the ellipse. If a and b represent the lengths of the semi-major and semi-minor axes respectively, then the value of (ab)^(2) is equal to :

If P_(1) and P_(2) are the lengths of the perpendiculars from any points on an ellipse to the major and minor axis and if a and b are lengths of semi-major and semi-minor axis respectively,then

The orbit of the earth around the sum is an ellipse. The sun is at one of the focus of this ellipse. If the length of its major axis of this ellipse. If the leght of its major axis of this ellipse is 30 million. Km. and eccentricity is 0,.0167 then find minimum and maximum distance of the earth from the sun.
