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.
