Note: \(\frac { dy }{ dx }\) is positive, if y increases as x increases and it is negative, if y decreases as x increases, dx, Marginal Cost: Marginal cost represents the instantaneous rate of change of the total cost at any level of output. If C(x) represents the cost function for x units produced, then marginal cost (MC) is given by, Marginal Revenue: Marginal revenue represents the rate of change of total revenue with respect to the number of items sold at an instant. x = f(t) and y = g(t), then (ii) f is strictly decreasing in (a, b), if f'(x) < 0 for each x ∈ (a, b). Home ; Video Lectures; Live Tutoring; Buy Course. Every continuous function on a closed interval has a maximum and a minimum value. Maximum and Minimum Value: Let f be a function defined on an interval I. y – y1 = \(\frac { -1 }{ m }\) (x – x1), where m = \(\frac { dy }{ dx }\) at point (x1, y1). Revision Notes on Application of Derivatives. The number f(c) is called an extreme value off in I and the point c is called an extreme point. Let us discuss some important concepts involved in the application of derivatives class 12 in detail. Note: If for a given interval I ⊆ R, function f increase for some values in I and decrease for other values in I, then we say function is neither increasing nor decreasing. Note f(c) > f(x), ∀ x ∈ I. The equation of normal to the curve y = f(x) at the point Q(x1, y1) is given by Second Derivative Test: Let f(x) be a function defined on an interval I and c ∈ I.

APPLICATION OF DERIVATIVES 195 Thus, the rate of change of y with respect to x can be calculated using the rate of change of y and that of x both with respect to t. Let us consider some examples. www.ncerthelp.com (Visit for all ncert solutions in text and videos, CBSE syllabus, note and many more) Mathematics Notes for Class 12 chapter 6. (i) A function f(x) is said to have a local maximum value at point x = a, if there exists a neighbourhood (a – δ, a + δ) of a such that f(x) < f(a), ∀ x ∈ (a – δ, a + δ), x ≠ a. parallel to the Y-axis and then equation of the tangent at the point (x1, y1) is x = x0.

Such a point is called a point of inflection. the amount by which a function is changing at one given point. Let Δx be the small change in x and Δy be the corresponding change in y. Here, f(a) is called the local maximum value of f(x) at the point x = a. Applications of the Derivative identifies was that this concept is used in everyday life such as determining concavity, curve sketching and optimization. (dx/dt), dS/dt = (d/dt)(6x2) = (d/dx)(6x2). Suppose cel is any point. f is decreasing in [a, b] if f'(x) < 0 for each x ∈ (a, b). Consider a function y = f(x), the rate of change of a function is defined as-.
