Chapter 25 – Parabola Exercise Ex. 25.1
Find the area of the triangle formed by the lines joining the vertex of the parabola to the ends of its latus- rectum
Find the equation of the lines joining the vertex of the parabola y2 = 6x to the point on it which have abscissa 24
Find the coordinates of points on the parabola y2 = 8x whose focal distance is 4
In given parabola
Given focal distance=a+x=4, so x=2
So points are (2, 4) and (2, -4)
Find the length of the lines segment joining the vertex of the parabola y2 = 4ax and a point on the parabola where the line-segment makes an angle to the axis
If the points (0, 4) and (0, 2) are respectively the
vertex and focus of a parabola, then find the equation of the parabola.
If the line y = mx + 1 is tangent to the parabola y2 = 4x,
then find the value of m.
