Question 1

What is a Derivative Calculator?

Accepted Answer

A derivative measures the instantaneous rate of change of a function — the slope of the tangent line at any point. Derivatives are the foundation of differential calculus and are used in physics (velocity, acceleration), economics (marginal cost), and optimisation.

Question 2

How does the Derivative Calculator work?

Accepted Answer

Power rule: d/dx[xⁿ] = n·xⁿ⁻¹ Then: Chain rule: d/dx[f(g(x))] = f'(g(x)) · g'(x) Then: Product rule: d/dx[f·g] = f'g + fg' Then: Common derivatives: d/dx[sin x] = cos x, d/dx[eˣ] = eˣ, d/dx[ln x] = 1/x.

Question 3

Can you give an example of how to use the Derivative Calculator?

Accepted Answer

Example: Input f(x) = x³ gives a result of f'(x) = 3x² (Power rule: bring down exponent, reduce by 1).
