Question No : 1 If the cost of X metres of wire is d rupees,then what is the cost of y metres of wire at the same rate? y=f(u) u=f(x) y=(2x+4)3 y=u3andu=2x+4 dy du =3u2 du dx =2 dy dx Problems 1. However, all you need to remember FACTS AND FORMULAE FOR CHAIN RULE QUESTIONS . Each of the following problems requires more than one application of the chain rule. Explanation are given for understanding. It states: if y = (f(x))n, then dy dx = nf0(x)(f(x))n−1 where f0(x) is the derivative of f(x) with respect to x. Exercises64 4. If f(x) = g(h(x)) then f0(x) = g0(h(x))h0(x). In fact, this problem has three layers. A R s. x y d. Direct Proportion: Two quantities are said to be directly proportional, if on the increase (or decrease) of the one, the other increases (or decreases) to the same extent. The chain rule enables us to answer this question without actually ever having to calculate z as an explicit function of u and v. It is usually much more effective to use the chain rule than to calculate the new function w (u,v) = z (x (u,v),y (u,v)). If so, graph your answer. The chain rule for powers tells us how to diﬀerentiate a function raised to a power. Download Chain Rule MCQ Question Answer PDF. Examples67 7. • The quotient rule • The chain rule • Questions 2. Two version of the chain rule are shown above. We must identify the functions g and h which we compose to get log(1 x2).

(a) y = u/v, if u = eax, and v = ebx (b) y = u/v, if u = x+1, and v = x−1 Exercise 5. This rule is obtained from the chain rule by choosing u = f(x) above. Solution: This problem requires the chain rule. We are nding the derivative of the logarithm of 1 x2; the of almost always means a chain rule. Cost is directly proportional to the number of articles.
