let students explore concepts by manipulating an expression—or a graphical representation of an expression—with things like sliders, buttons, and checkboxes. When you wrap the Manipulate command around an existing calculation, Mathematica automatically creates a sophisticated interface that lets you and your students change values and see what happens in real time. It’s truly empowering!
Now students can interact with everything from two-dimensional trajectory paths…
to Riemann sums…
to the phases of the planets…
to almost anything else you can imagine. See the Wolfram Demonstrations Project for thousands of free ready-to-use examples.
