प्रश्न

Find the co-ordinates of the focus, vertex, equation of the directrix, axis and the length of latus rectum of the parabola

x2 = 8y

योग

उत्तर

x2 = 8y

x2 = 4(2)y

∴ a = 2

Vertex (0, 0) (0, 0)
Focus (0, a) (0, 2)
Axis y-axis x = 0
Directrix y + a = 0 y + 2 = 0
Length of Latus rectum 4a 8
