And Another doubt how to sole this problem in differentiation.
A circular cylinder is to fit inside A Sphere Of Radius 10 cm. Calculate the maximum possible volume of the cylinder.(it is possible best to take as your Independant V ariable the height or or half the height of the cylinder.

so how do we know that f(x) is more than 3 divided 4 why not less than.

because the turning point is the minimum point. When the point is the minimum, whole of the graph will lie above the minimum point.
If the point is maximum, whole of the graph will lie under the maximum point.
