Find the graph and all the characteristics (centre, vertex, covertice, length of minor and major axis, length of latus rectum, equation of directrices and latus
rectum) of the graph with equation 8x^2 + 3y^2 = 24.

The given equation is 16x

Herethe denominator of

is greater than the denominator of

Therefore, the major axis is along the y-axis while the minor axis is along the x-axis.

On comparing equation (1) with

Therefore, the coordinates of the foci are (0,±

The coordinates of the vertices are (0,±4)
