Here's the applet we looked at in class on Friday that shows pointwise convergence of Taylor series. Feel free to use this applet to generate graphs for your lab writeup. (Some tips for navigation: Shift-dragging on the background will move the whole picture around. The mouse wheel zooms in and out. You can shift-drag the axes to change the scale. Use the blue/white buttons next to object definitions in the left sidebar to turn them on or off.)
