what is the product rule in math The product rule is if the two parts of the function are being multiplied together and the chain rule is if they are being composed For instance to find the derivative of f x x sin x you use the product rule and to find the derivative of g x sin x you use the chain rule
The product rule formula is given as f x u x v x u x v x u x v x where f x u x and v x are derivatives of functions f x v x and u x What is Product Rule Formula Product rule derivative formula is a rule in differential calculus that we use to find the derivative of product of two or more functions We have two functions cos x and sin x multiplied together so let s use the Product Rule fg f g f g Which in our case becomes cos x sin x cos x sin x cos x sin x We know from Derivative Rules that sin x cos x cos x

In calculus the product rule or Leibniz rule or Leibniz product rule is a formula used to find the derivatives of products of two or more functions For two functions it may be stated in Lagrange s notation as Product rule The product rule is a formula that is used to find the derivative of the product of two or more functions Given two differentiable functions f x and g x where f x and g x are their respective derivatives the product rule can be stated as or using abbreviated notation The product rule can be expanded for more functions
The Product rule tells us how to differentiate expressions that are the product of two other more basic expressions d d x f x g x d d x f x g x f x d d x g x Basically you take the derivative of f multiplied by g and add f The product rule is an essential derivative rule used to find the derivative of a function that can be expressed as a product of two simpler expressions A great example of this type of function is h x x 3 2 x 1 x 3 4 x 2 1
