Below is the graph of f(x) = cos(x). [br]The point labeled "SlopeOfTheTangentLine has a y value that is the slope of the line tangent to the point "DragMe" [br]You can graph the derivative of this function by[br]1. Clicking the "Begin Graphing the Derivative" button, then[br]2. Dragging the point "DragMe"[br]The graph of the f '(x) will be traced onto the screen. [br][br]When you click "Stop Graphing The Derivative" the graph will disappear. [br][br]Change the equation of f(x) in the top left corner in order to change the function.
