Points where the derivative of a function vanishes are called . STATIONARY points. Thus x = 2,5, in the first example, x = 1 in the second example and x = 0 in the third example are all stationary points. A stationary point can be a minima (as in the first example) or a maxima (as in the second example) or a cusp (as in the third example). ................
