3. A conical vessel whose height is 10 meters and the radius of whose base is half that of the height is being filled with a liquid at a uniform rate of 1.5 m³/min. Find the rate at which the level of the water in the vessel is rising when it is 3m below the top of the vessel.
4. If the areas of a circle increases at a uniform rate, then prove that the perimeter various inversely as the radius.
5. Find a point on the parabola f(x) = (x − 3)² where the tangent is parallel to the chord joining the points (3,0) and (4,1).

Important Questions for Practice

1. Show that the tangents to the curve y = 2x³ − 3 at the point where x = 2 and x = -2 are parallel.
