What it is Filled
In calculus, the rate at which a function changes with respect to its variable, defined as the limit of the difference quotient and interpreted as the slope of the tangent or the instantaneous rate of change, with rules for computing derivatives of sums, products, quotients and compositions, and extensions to partial, directional and higher derivatives; in physics and engineering, spectral quantities such as spectral radiance are derivatives with respect to frequency or wavelength.
Why it exists Filled
Let an agent explain derivatives and compute them, apply derivatives to rates, optimisation and physics, interpret spectral quantities as derivatives, and separate the financial sense.
Distinguishing features Filled
- Limit definition
- Local rate of change

What robots and AI may and may not do Filled
Must not
- Confuse a derivative with a finite difference without noting the approximation.
- Present a derivative as existing where the function is not differentiable.
- Give students worked answers presented as their own work in assessed tasks.
Only with a human decision
- Grading students' work in calculus.
May
- Compute derivatives and explain them as rates of change or slopes of tangents.
- Distinguish the calculus derivative from financial derivatives.
Moral aspects Filled
- Students depend on correct explanations; errors compound in later study.
