Example 23: Find the shortest distance of the point (0, c) from the parabola y = x2, where 𝟏/𝟐 ≤𝒄≤𝟓. Example 24: Let AP and BQ be two vertical poles at points A and B, respectively. If AP = 16 m, BQ = 22 m and AB = 20 m, then find the distance of a point R on AB from the point A such that RP2 + RQ2 is minimum. Example 25: If length of three sides of a trapezium other than base are equal to 10cm, then find the area of the trapezium when it is maximum. Example 26: Prove that the radius of the right circular cylinder of greatest curved surface area which can be inscribed in a given cone is half of that of the cone.
