Chain Rule Questions is an an essential part for Competitive Exams like Banking, Insurance, SSC and Railways Exams. The Chain Rule
2. 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. anytime you want. Most problems are average. ). Hint : Recall that with Chain Rule problems you need to identify the “inside” and “outside” functions and then apply the chain rule. Covered for all Bank Exams, Competitive Exams, Interviews and Entrance tests. Show Solution For this problem the outside function is (hopefully) clearly the exponent of 4 on the parenthesis while the inside function is the polynomial that is being raised to the power. When do you use the chain rule? ( ) ( ) 3 1 12 24 53 10 If you're seeing this message, it means we're having trouble loading external resources on our website. Differentiating using the chain rule usually involves a little intuition. After the chain rule is applied to find the derivative of a function Fx( ), the function Fx fx x x′( )==( ) 4 cos 3 sin 3 3(( ))3⋅− ⋅(( )) is obtained. Chain rule: Trigonometric types; Parts (a) and (b): Part (c): 4) View Solution. The chain rule is a method for finding the derivative of composite functions, or functions that are made by combining one or more functions.An example of one of these types of functions is \(f(x) = (1 + x)^2\) which is formed by taking the function \(1+x\) and plugging it into the function \(x^2\).
