Osculating Circles to Graphs of Functions

This app allows you to plot function graphs and their osculating circles. In the upper input field the equation of the function can be defined. The other input fields are used to select the area to be drawn. The point (black) where the osculating circle (blue) is shown can be moved on the graph (black) by dragging it with the mouse. In addition, the tangent (red) and the line segment between the center of the circle and the point of tangency are drawn.
