Chain Rule Calculator

The Chain Rule is a formula for differentiating composite functions — functions of the form h(x) = f(g(x)). It is one of the most important rules in calculus and is essential for differentiating all but the simplest functions

The calculator uses the standard published formula for chain rule. Results are accurate to the precision of the inputs you provide. For financial, medical, or legal decisions, always verify with a qualified professional.

This calculator works with inches. You can enter values in the units shown — the calculator handles all conversions internally.

The core formula is: If h(x) = f(g(x)), then h'(x) = f'(g(x)) · g'(x). Each step in the calculation is shown so you can verify the result manually.
