Derivative as a function
- Malin Christersson
The line shown in the construction below is the tangent to the graph at the point A. The slope of the tangent line is the y-value of the point P. Drag the point A to see the trace of the point P, this trace is the graph of the derivative function.
Note that the point P does not move when changing the slider e, hence there are infinitely many functions giving rise to the same derivative.
