(2) If `f` is differentiable at critical point, then the value of derivative of `f` at critical point is :

What is critical point?

For a gas obeying the van der Waals' equation, at the critical point

Which of the following is true at the critical point?

In the curve y = 2+12x-x^3 , find the critical points.

Between any 2 real roots of a real valued differentiable function f(x), there lies atleast one critical point of f(x) is a conclusion of

Assertion : At critical point, the densities of gaseous and liquid states become same. Reason : At critical point, gases behave ideally.
