Although the name itself is suggestive, we introduce the concept of maxima and minima here through a simple example: Consider an arbitrary function f(x).. i.e. Maxima and minima occur alternately, i.e., between two maxima there is one minima and vice-versa. Mathematics is like checkers in being suitable for the young, not too difficult, amusing, and without peril to the state. The common task here is to find the value of x that will give a maximum value of A. We have already seen in the above example that, using first derivative test, x =1 is neither a point of local maxima nor a point of local minima and so it is a point of inflection. So the edges of the interval will act as critical points along with the ones we find using the first derivative.
