The Graph of a Derivative
The animation below shows the graph of (in black) and of its derivative, (in green). The coordinates of point B (red) are the x- and y-coordinates of the derivative, while the coordinates of point A (blue) are the coordinates of . A segment of the tangent line at each position of A is shown in yellow and its slope is labeled in pink. Press the Animation button to start or stop the animation (it moves slowly, so give it a couple of seconds to start). Reset to the beginning () usng the Reset button.
