Chords and Tangents of Polynomials
You can use this display to see how the gradient of a chord (or secant) approaches
the gradient of a tangent as the length of the chord approaches zero.
Having defined your polynomial, with the blue sliders, you can set the tangent point with the "tangent x" slider, and then drag an approaching point towards it with the "approach x" slider.
