Chain rule with e math. F x f g x g x the chain rule can also be written using leibniz s notation given that a variable y depends on a variable u which is dependent on a variable x. We will also give a nice method for writing down the chain rule for. The exponential rule is a special case of the chain rule. In particular we will see that there are multiple variants to the chain rule here all depending on how many variables our function is dependent on and how each of those variables can in turn be written in terms of different variables.

The exponential rule states that this derivative is e to the power of the function times the derivative of the function. Using the chain rule and the quotient rule we determine begin equation frac dg dx 3 left frac 3x 2 2 2x 3 right 2 left frac 2x 3 6x left 3x 2 2 right 2 2x 3 2 right end equation which simplifies to begin equation frac dg dx frac 6 left 2 3 x 2 right 2 left 2 9 x 3 x 2 right 3 2 x 4 end equation as desired. In the section we extend the idea of the chain rule to functions of several variables. Chain rule step by step derivative example.

The chain rule is as follows. F g f g g let f f g f x f g x then the chain rule can also be written in lagrange s notation as.
