Rate of Change of A Quantity

Example 1 The function f (x) =cosx takes on its (local and absolute) maximum value of 1 infinitely many times, since cos2nπ=1 for any integer n and −1≤cosx ≤1 for all x. Likewise, cos( 2n +1)π=−1 is its minimum value, where n is any integer. Example 2 The graph of the function f (x) =3x4 −16x3 +18x2 −1≤x ≤4 is shown.

Applications of Differentiation 2 The Extreme Value Theorem If f is continuous on a closed interval[a,b], then f attains an absolute maximum value f (c) and an absolute minimum value )f (d at some numbers c and d in []a,b.Fermat’s Theorem If f has a local maximum or minimum atc, and if )f ' (c exists, then 0f ' (c) = . Critical Number A critical number of a function f is a number cin …

APPLICATIONS OF DERIVATIVES Derivatives are everywhere in engineering, physics, biology, economics, and much more. In this chapter we seek to elucidate a number of general ideas which cut across many disciplines. Linearization of a function is the process of approximating a function by a line near some point.

point. For example, if there is a stationary point at x = 2, we may choose x = 1.9 and x = 2.1. 2. Calculate for each of these two values of x. 3. By observing the sign change of , we can deduce the nature of the stationary point. 4. If the gradient changes from positive to negative before and after the stationary point, the point is a maximum. 5.

Application 1 : Exponential Growth - Population. Let P (t) be a quantity that increases with time t and the rate of increase is proportional to the same quantity P as follows. d P / d t = k P. where d p / d t is the first derivative of P, k > 0 and t is the time. The solution to the above first order differential equation is given by.

DIFFERENTIAL EQUATIONS The general solution of a differential equation involves an arbitrary constant (or constants), as in Example 2. However, there may be some extra conditions given that will determine the constants and, therefore, uniquely specify the solution.

Some of the most important applications of differential calculus are optimization problems. In these, we are required to find the optimal (best) way of doing something. EXAMPLES Here are some examples of such problems that we will solve in this chapter. What is the shape of a can that minimizes manufacturing costs?

If there is no change in the sign of the gradient, the stationary point is a point of inflexion. Example 2. A curve whose equation is has stationary points at ( ...
