How to Submit a Curve
The National Curve Bank (NCB) students, staff and faculty welcome submissions that illustrate, in a way not possible on the printed page, the features of an interesting curve. A typical submission includes an animated gif file that displays the curve and, optionally, an accompanying text file that describes unusual features of the curve, discusses historical information related to it, or provides interesting applications of its use. We ask that your submission be relatively brief, generating hard copy that is not more than one page in length.
Submission Details
To submit a curve to the NCB:

1. Create the curve using the software of your choice; for example, Mathematica, Mathcad, Maple, Derive, or a variety of graphing calculators.

2. Animate the curve by creating a sequence of images saved as gif files and then using the appropriate software (for example, Mathematica, Adobe PhotoShop, Adobe ImageReady, or GIF Construction Set).  Save the animation as a single animated gif file.  Be sure to use the < .gif > extension when you make your final "Save As."

3. Create a separate text file, if you’d like, with interesting information about the curve (for example, unusual features, historical information, or special applications).  Save the text in a separate file; for example, MS Word (.doc) or as plain text.

4. Include your name, affiliation and address, e-mail address, the name of the curve, the equations you used to create it, and a very brief description of the files you are sending. Attach the animated gif file and the text file (if applicable) to this e-mail.  Please include references you have used.

5. Send the file(s) as e-mail attachments, using the email address of the NCB:

Guidelines for Creating the Curve

1. Create a graphic that is 250 to 350 pixels wide, unless the animation requires a particularly wide display. In this case, do not exceed 600 pixels.

2. If your graphing software allows for color and varying curve thickness, make use of these features. In particular, do not use one-pixel-thick curves.

3. If your graphing software does not save graphics in a gif format, paste the images into a graphics program (for example, Adobe PhotoShop or Paint Shop Pro) and save them there.

4. In animating the curve, use a sufficient number of images and an appropriate delay time between them to ensure that the resulting animation is relatively smooth.
