University Math Help. : (x + 1)½ is the outer function and x + 1 is the inner function. √ X + 1  The Chain rule of derivatives is a direct consequence of differentiation. Step 2:Differentiate the outer function first. −1 Step 4 Multiplying 4x3 by ½(x4 – 37)(-½) results in 2x3(x4 – 37)(-½), which when worked out is 2x3/(x4 – 37)(-½) or 2x3/√(x4 – 37). D(3x + 1) = 3. We’ll start by differentiating both sides with respect to $$x$$. Therefore sqrt(x) differentiates as follows: Step 3. Using the chain rule and the derivatives of sin(x) and x², we can then find the derivative of sin(x²). All functions are functions of real numbers that return real values. The derivative of ex is ex, so: 21.2.7 Example Find the derivative of f(x) = eee x. In order to use the chain rule you have to identify an outer function and an inner function. The outer function is √, which is also the same as the rational exponent ½. (10x + 7) e5x2 + 7x – 19. Note: keep 4x in the equation but ignore it, for now. Even though we had to evaluate f′ at g(x)=−2x+5, that didn't make a difference since f′=6 not matter what its input is. dF/dx = dF/dy * dy/dx Tip You can also use this rule to differentiate natural and common base 10 logarithms (D(ln x) = (1/x) and D(log x) = (1/x) log e. Multiplied constants add another layer of complexity to differentiating with the chain rule. The chain rule enables us to differentiate a function that has another function. Different forms of chain rule: Consider the two functions f (x) and g (x). Chain Rule The chain rule is a rule, in which the composition of functions is differentiable. Differentiate using the product rule. Watch the video for a couple of chain rule examples, or read on below: The formal definition of the chain rule: The patching up is quite easy but could increase the length compared to other proofs. That isn’t much help, unless you’re already very familiar with it. Then the Chain rule implies that f'(x) exists, which we knew since it is a polynomial function, and Example. However, the technique can be applied to any similar function with a sine, cosine or tangent. The results are then combined to give the final result as follows: As you will see throughout the rest of your Calculus courses a great many of derivatives you take will involve the chain rule! D(4x) = 4, Step 3. D(e5x2 + 7x – 19) = e5x2 + 7x – 19. Label the function inside the square root as y, i.e., y = x2+1. D(5x2 + 7x – 19) = (10x + 7), Step 3.
