![]() ![]() The chain rule calculus is used to differentiate a combination of two functions. The comparison between the chain and quotient rules can be easily analysed using the following difference table. ![]() Mathematically, it is simply expressed by,ĭ/dx = f’(x) Comparison between Chain rule and Quotient rule If a function is defined implicitly, the implicit differentiation is used to find the rate of change. If two functions are multiplied with each other, the derivative of these functions can be written as Like chain rule derivative, the implicit differentiation and product rule are also used to find the derivative of a function. By using this step, the chain rule calculator will provide the derivative of cos x quickly and accurately which will be –sin x. Now at the last step, click on the calculate button.Review the input so that there will be no syntax error in the function.Choose the variable to calculate the rate of change, which will be x in this example.Write the expression of the function in the input box such as, cos x.For example, to calculate the derivative of cos x, the following steps are used by using this calculator. You can find it online by searching for a derivative calculator. It is an online tool that follows the chain rule derivative formula to find derivative. The derivative of a combination of two or more functions can be also calculated by using chain rule derivative calculator. Applying Chain rule formula by using calculator Now substituting the values of dy/du and du/dx, we get, Now finding the derivative of both functions, In the above equation, the 2x can be replaced by another variable u. So to calculate the derivative of cos 2x, we will use the following steps, The derivative of cos 2x can be calculated by using the combination law of derivatives. Since the given function is an exponential function then we can use the power rule of derivative also. Now substituting the values of dy/du and du/dx. Now by using chain rule, we will calculate the derivative of both function y and u one-by-one. In the above equation, x^3 can be replaced by a variable u. The chain rule is one of the methods to evaluate derivative of e^^3. To calculate the derivative of e^x^3, we can use different techniques. Let’s understand the following examples by applying the chain rule of derivative. Multiply the derivative of y and u together as dy/du × du/dx.Calculate the derivative of both functions u and y one-by-one.Apply the derivative by using the chain rule formula.Identify the combination of two functions and name them as y=f(u) and u=g(x) functions.These steps assist us to calculate the derivative of two or more functions in fraction. The implementation of the chain rule of derivative is divided into a few steps. Instead of using the product rule formula, the chain rule helps to find the derivative more easily. dv/dx is the derivative of v with respect to x.du/dv is the derivative of u with respect to v.The formula to calculate derivative of a combination of three functions is, The chain rule can be used to calculate the derivative of such a function. ![]() If there are three functions f(x), g(x) and h(x) combined together. The chain rule can be used for three functions combined together. du/dx is the derivative of u with respect to x.dy/du is the derivative of y with respect to u.Then the chain rule formula is expressed as: If two functions f(x) and g(x) are in a combination form such as f(x) is a function of g(x) i.e. The variable u is used to replace the second function so that it can be easily differentiated. “The derivative of f(g(x)) is equal to the derivative of y with respect to u multiplied with the derivative of u with respect to x, where y=f(u) and u=g(x).” It calculates the rate of change of a function in relation to the other function.īy definition, the chain rule for a function f(g(x)) is stated as: The chain rule is a rule of expressing derivative of a function which is a combination of two functions. All of these rules are important to find the rate of instantaneous change of a function. There are different rules of differentiation in calculus. Let’s understand how to apply the chain rule to find a derivative. For this, the chain rule formula is used to find the derivative of two combined functions. Sometimes, we have to deal with a combination of two functions. There are some derivative rules to calculate the rate of change of different functions like exponential, trigonometric, or logarithmic functions, etc. When calculating the composition \(f \circ g\), there is one internal function \(g\) and one external function \(f\), and youĬhange the order, very often the outcome varies.The derivative is a fundamental concept of calculus that involves the rate of the instantaneous change in a function. ![]()
