Looking through the demos, I see some things that as far as I know are not documented or hardly mentioned in any of my reading about graphing calculator. Is...

Graphing variables, such as t (for parametric lines) and u and v (for parametric surfaces) are sort of like paint brushes which are applied to the vectors you...
I am looking at examples/two dimensions/tangent line to a function and would like to know how they entered the notation for the derivative of f(x) vertical bar...
... I lost the original example, but here's an attempt to do a version where the length of the arrow is equal to the value of the derivative.  To get the...
Suppose that I click on a contour plot and begin tracing around a level curve. Graphing calculator displays the x and y coordinates of where my cursor is....
... Although GC doesn't have a way to access the cursor position for use in equations, there are a variety of not-too-difficult workarounds.  For example,...
Here's a way to show the 3D function corresponding to the 2D one. Any function can be entered in. As you drag the 2D point around (following contours if you...
Just stumbled upon an interesting-looking plot here. If you've got a fairly advanced computer, GC will do beautiful, razor- sharp clipping that let's you make...

The basic idea is to plot cylinders whose walls are at the distance given by the solid of revolution whose volume we're trying to find. Aligning the solid...
By just rearranging the equations a little, we get the relationship between the volumes of a cylinder, sphere, and double cone: i.e., 3:2:1. Interesting that...
A few refinements, at the expense of very slightly complicating the equations, but simplifying the visuals: If we want to clip off two curves at their...
Here are some view of a the solid resulting from rotating the space between the cosine and the sine of 2πz around the z axis. I've used a smaller plotting...
Mystery solved. I hit the keyboard accidentally and wiped out the highlighted parameter list below. Currently, each list has to be updated to change the number...
This is still graphing reasonably fast. I still need to put back the volume calculations. Also, integrals will have to be done on a case by case basis....
