Just another version of the least-squares file. Once again, the key point is that contrary to the impression created by calling this a "best-fit" line, to get...

Ron, Please excuse the nagging here, but here's something which I hope will be fixed in the new release: I know I've gotten an explanation about the D_V( )...
Trying to make it a little easier to understand what's going on in Strang's instructive comparison of vector-projection and least-square line-fitting. Work in...
I'm trying to write code that will produce little pie wedges -- sectors of a circle -- centered at a variable user-specified point. As the base point moves...
... Are you trying to have the point move around within the circle? If you could post the file, I'd have a better idea. Below is a way to graph sectors. I'm...
I'm having the usual pesky problem with getting the angles to run right. Also, the following doesn't work correctly if M isn't at the origin. The latter...
I think I've managed to get the sectors to work right. I wish I could use the function for the interior of the angle in the inequalities. I have to expand each...
Here the function can be modified to whatever you want. You can ignore the A, B, and C constants if you want, also. Shows that the two forms of the secant line...

Work in progress towards an in-depth analysis of derivatives via the secant line. Want to show convergence of the equation towards the Taylor series at that...
Here, I've added lines (the purple dashed line segments on top of the solid light gray lines) illustrating the two terms of the interpolating polynomial (the...
I think Ron may have warned me not to do this kind of thing, but it certainly would be in keeping with accepted usage. I'd like to be able to use the...
... Yes, I've noticed this as well -- behavior when one of the many reserved symbols are used in this way can be unpredictable. Will sometimes work, and at...

Hi all GC-users, I have an issue with Drag and Drop graph clippings. If I graph a simple ineq eg. 1 < x < 2 and drag the graph to finder the generated pict...

By making the x-parameter run a lot fast than the y-parameter you can effectively flatten out the regions of the curve around the extrema. Have to work out the...
