Intermediate~22 min19 steps
Grab the tangent line and drag it — the derivative is the number under your finger.
You’ll learn
- Interpret a derivative as an instantaneous rate of change
- Connect the slope of a tangent line to the value of the derivative
- Explain why the limit definition needs h to approach zero
- Differentiate polynomials, products and composite functions with the rules
- Read maxima, minima and inflection from where a derivative is zero
- Recognise the points where a function has no derivative
