Zoom graphing utility

Drag the corners of the box to adjust the portion of the graph that will be shown on the right side of the window. After dragging, point A must be above and to the left of point B.

Sine of theta, divided by theta

Drag the point A to change the value of θ. Notice what happens to the value of sin(θ)/θ, as θ gets closer to 0.

Secant Lines 1

Click the check boxes, one at a time, and adjust the values on the sliders that appear. Notice the corresponding changes in the secant line.

Riemann Sums

Drag the sliders to change the Riemann Sum. Notice that as the number of rectangles increases, the collection of rectangles more closely matches the region between the graph of f(x) and the x-axis.

Plot sequences

Plot the terms of a sequence and the partial sums of the corresponding series

Parametric Equations

Drag the point t in the panel on the left side of the window, and notice the corresponding changes to the point (f(t),g(t)) in the panel on the right side of the window.

Spirograph simulator

To erase the drawing, move the "Draw" slider all the way to the left. After clicking on a slider, you can use the arrow keys on your keyboard to fine-tune the value of that slider.
