Explanation 1) Concept: Use the given information to find the equation of curve. 2) Calculation: Consider the isosceles triangle ∆ O P Q which is formed by the line drawn from the origin to any point x , y on the curve and extended tangent from that point which meet at x - axis. The side O P of a triangle is given by, O P = x - 0 2 + y - 0 2 = x 2 + y 2 = a 2 2 + y 2 = a 2 4 + y 2 From the figure, height of the triangle is h Here, O P = O Q Thus, by using Pythagoras rule, x 2 + y 2 = a 2 4 + h
