The Product Rule; 4. Audience A maximum is a high point and a minimum is a low point: In a smoothly changing function a maximum or minimum is always where the function flattens out (except for a saddle point). Applications of the Derivative. Then, check for 0 = 12(0)2 4 = 4 < 0 1 = 12(1)2 4 = 8 > 0 1 = 12(1)2 4 = 8 > 0 Thus, there is relative maximum at = 0, and there are relative minima at = 1 and = 1. 1.

Consider the graph shown below. To find this value, we set dA/dx = 0. 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. Local maximum and minimum values are also, Identify the location of various maxima and minima and classify as. (ii) x = c may be a point of local minima if f c ′( ) 0 = and f ″(c) > 0 during this case, f (c) is local minimum value of f. (iii) The test fails if f ′(c) = 0 and f ″(c) = 0. during this case, we return to the primary derivative test and find whether c may be a point of local maxima, local minima… The maxima or minima can also be called an extremum i.e. In Mathematics, the derivative is an expression that gives the rate of change of a function with respect to an independent variable. 2 points Application of Derivatives: Maxima & Minima (Seo Chapter 4 Section 3 & 5, p.366, 390) 2 Let f(x) - 6x + 8.
