Find the area of the triangle formed by the lines joining the vertex of the parabola to the ends of its latus- rectum

Solution 21 Question 22 Solution 22  Question 23 Solution 23 Question 24 Solution 24 Question 25 Solution 25 Question 26 Solution 26 Question 27  Solution 27 Question 28

Find the equation of the lines joining the vertex of the parabola y2 = 6x to the point on it which have abscissa 24

Solution 28 Question 29

Find the coordinates of points on the parabola y2 = 8x whose focal distance is 4

Solution 29

In given parabola

a=2

Given focal distance=a+x=4, so x=2

So points are (2, 4) and (2, -4)

Question 30

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

Solution 30 Question 31

If the points (0, 4) and (0, 2) are respectively the vertex and focus of a parabola, then find the equation of the parabola.

Solution 31 Question 32

If the line y = mx + 1 is tangent to the parabola y2 = 4x, then find the value of m.
