Hello, I was wondering if anybody had algebra, trigonometry, linear algebra or calculus material that I can use to teach a class on Graphing Calculator? ...
I haven't got much time to point out much now, but there are a lot of more-or-less organized files in the "Files" section. You just click on "Files" and then...
Hi Graphing Calc Users, I've not used this software before but I noticed on the tour page there is "drag algebra". I was wondering if you've taken that concept...

I didn't give GC enough credit. Fractions with different denominators can be added directly via "drag algebra" as follows:   Pull over to the right as...
John, Sounds interesting, and I'd like to see the demo, but I haven't been able to view either file so far. I get this for the .mpg file  and this  for...
Hey Chris, I'll try transcode it to another format tonight. I'm not sure which are well supported codecs on Macs and Windows so its entirely possible that...
John, I couldn't use the first two links, http://peberdy.ca/jp/projects/ file/demo1.avi :  I was able to see the image dump, though, and it looks...
Could anyone advise me on how I can operate in 3D mode? When I attempt to enter co0ordinates as shown in the help files,"you enter this," all attempts are...
... If you can attach a file or send it to me, it would a lot easier to zero in on the problem. Are you sure you have GC 3.5? To find out, select "About...
... Were you trying to graph this in 3D? The problem with that is that you have no y variables in the equations. If you put one in, even if multiplied by...
... You have to enter "=" and then another 3-vector (Math/3-Vector), and then fill in the fields of that 3-vector with the function you want to plot. For...
You can always draw the associated field lines for a vector function by just forming the related ordinary differential equation by taking the "Total...
Although you can't do field lines for 3D vector fields in GC 3.5, you can add a surface from which to draw the arrows. The surface could be movable, allowing...
Here's a vector field with the same animated y-term added to each component. You can drag the mouse in the graph to see the field line going through that...

The charges and radii of the spheres are adjustable via sliders. The "n" animation button controls the distance--Click the arrow to animate. The yellow arrows...
Here's an inverse-square force field, such as you might see from an electrically charged sphere. I've adjusted the resolutions of the surface and of the vector...
I'm trying to find a way to not have arrows plotted with the circles, so that on the whole the arrows will be longer so that we can see the vector summation at...
Although the vectors are getting added correctly, the blue arrows as shown aren't the correct length. I'm still not sure how to fix this. I think the problem...
At least in this simple case, the parallelogram addition of the vectors is represented correctly. I have to have both circles the same size, or it's off:...
By using an "if" statement on of its arguments, we can make the vector function as a whole undefined inside of a certain distance of the . This ensures that GC...
It looks like by adjusting the relative size of the "clipping circles", the vector parallelograms can be made to come out right. If I can figure out the...
Hi List, Regarding the click and drag math program I mentioned last week I just wanted to let you know that I've put a couple videos on my website in a flash...
