chain rule

Nested function differentiation

The chain rule is a formula in calculus for finding the derivative of a composite function—a function built from other functions.

If y depends on u and u depends on x, the chain rule states that dy/dx equals dy/du times du/dx.

Use the chain rule to differentiate sin(x²).

The rule extends to functions with multiple layers of composition.
