What is the Chain Rule?
The chain rule is a fundamental theorem in calculus used to find the derivative of composite functions. Our chain rule calculator applies this essential differentiation technique to solve complex derivative problems step-by-step. When you have a function composed of other functions, like f(g(x)), the chain rule provides the method to find its derivative efficiently.
The chain rule calculator is indispensable for students learning calculus, as it handles the most challenging aspect of differentiation - composite functions. Whether you're dealing with trigonometric, exponential, logarithmic, or polynomial compositions, this calculator provides accurate results with detailed explanations.
Chain Rule Calculator Formula
d/dx[f(g(x))] = f'(g(x)) · g'(x)
Chain Rule Formula
Leibniz Notation:
dy/dx = (dy/du) · (du/dx)
Alternative Form:
(f ∘ g)'(x) = f'(g(x)) · g'(x)
Our chain rule calculator uses this fundamental formula to differentiate composite functions. The key insight is that you multiply the derivative of the outer function (evaluated at the inner function) by the derivative of the inner function. This process can be extended to multiple compositions.

Chain Rule Calculator Examples
Example 1: Polynomial Composition
Function: f(x) = (x² + 3x + 1)⁵
Find: f'(x)
Solution:
Let u = x² + 3x + 1, then f(x) = u⁵
f'(x) = 5u⁴ · u'
u' = 2x + 3
f'(x) = 5(x² + 3x + 1)⁴(2x + 3)
Example 2: Trigonometric Composition
Function: g(x) = sin(x² + 1)
Find: g'(x)
Solution:
Let u = x² + 1, then g(x) = sin(u)
g'(x) = cos(u) · u'
u' = 2x
g'(x) = cos(x² + 1) · 2x
Example 3: Multiple Chain Rule Application
Function: h(x) = e^(sin(x²))
Find: h'(x)
Solution (Multiple Applications):
Let v = x², u = sin(v), then h(x) = e^u
h'(x) = e^u · u' (first chain rule)
u' = cos(v) · v' (second chain rule)
v' = 2x
Therefore: u' = cos(x²) · 2x
h'(x) = e^(sin(x²)) · cos(x²) · 2x

Common Chain Rule Calculator Mistakes
Mistakes to Avoid:
Forgetting the Inner Derivative
Always multiply by the derivative of the inner function. This is the most common error.

Properly identify which function is outer and which is inner before applying the rule.
Multiple Chain Rule Confusion
When functions have multiple compositions, apply the chain rule systematically from outside to inside.
Best Practices:
Use Substitution Method
Let u = inner function, then differentiate step by step for clarity.
Work from Outside In
Always start with the outermost function and work your way inward systematically.

Chain Rule Calculator FAQ
When should I use the chain rule calculator?
Use the chain rule calculator whenever you need to find the derivative of a composite function - that is, a function within another function. Examples include (x² + 1)³, sin(2x), e^(x²), or any function where one function is nested inside another.
How does the chain rule calculator handle multiple compositions?
Our chain rule calculator applies the rule recursively for functions with multiple levels of composition. For example, with sin(e^(x²)), it first differentiates sin(u) where u = e^(x²), then differentiates e^v where v = x², creating a chain of derivatives multiplied together.
Can the chain rule calculator solve implicit differentiation problems?
Yes! The chain rule calculator can handle implicit differentiation problems where the chain rule is needed. When differentiating equations like x² + y² = 1, the calculator applies the chain rule to terms involving y, treating y as a function of x.
What's the difference between the chain rule and product rule?
The chain rule is used for composite functions (function within a function), while the product rule is used for products of functions. Use chain rule for f(g(x)) and product rule for f(x)·g(x). Sometimes you need both rules in the same problem!
How accurate is the chain rule calculator?
Our chain rule calculator provides mathematically exact results using symbolic computation. It doesn't use numerical approximations, so the derivatives are precise algebraic expressions. The step-by-step solutions also help you verify the accuracy of each calculation step.
Can I use the chain rule calculator for higher-order derivatives?
Yes, the chain rule calculator can compute higher-order derivatives of composite functions. For second derivatives and beyond, the calculator applies the chain rule multiple times and combines it with the product rule as needed, showing each step clearly.
