Rule (I): Differentiation of a constant function is zero i.e., d/dx (c) = 0 Rule (II): Let f(x) be a differentiable function and let c be a constant. Then c.f(x) is also differentiable such that , This is the derivative of a constant times a function is the constant times the derivative of the function.

⇒ Generally matter expands on heating and contracts on cooling. In case of water, it expands on heating if its temperature is greater than 4°C. In the range 0°C to 4°C, water contracts on heating and expands on cooling, i.e. g is negative. This behaviour of water in the range from 0°C to 4°C is Read more about Anomalous Expansion of Water[…]

If y = f(x), then dy/dx the derivative of y with respect to x, is itself, in general or function of x and can be differentiated again. To fix up the idea, we shall call dy/dx as the first order derivative of y with respect to x and the derivative of dy/dx w.r.t. x as Read more about Higher Order Derivatives[…]
