In calculus we have learnt that when y is the function of x, the derivative of y with respect to x i.e dy/dx measures rate of change in y with respect to x.Geometrically, the derivatives is the slope of curve at a point on the curve. In calculus, we use derivative to determine the maximum and minimum values of particular functions and many more. On an interval in which a function f is continuous and differentiable, a function will be, Increasing if fꞌ(x) is positive on that interval that is, dy/dx >0, Decreasing if fꞌ(x) is negative on that interval that is, dy/dx < 0. The derivative is called an Instantaneous rate of change that is, the ratio of the instant change in the dependent variable with respect to the independent variable. The function $V (x)$ is called the potential energy. These are just a few of the examples of how derivatives come up in At x= c if f(x) ≤ f(c) for every x in the domain then f(x) has an Absolute Maximum.
