I'm trying to write a program (see code below) that produces a circle with a sector identified by two radii and a small arc connecting the radii (to emphasize the angle, which I will later add a "theta" label to). The sector needs to be shaded, and I prefer not to have any axes showing; I think I can do some of this by right-clicking on the figure after it is rendered by Maple, but it seems to me that the code should be able to handle all of this as well. I will be using the resulting figure in a homework set that I am producing for a trigonometry class.

If anyone can advise me about how to create the tool that I describe below, that would be great. I am a novice to Maple and object-oriented programming, but I can program in C and I suspect that I can write a Maplet, if that is indeed the best way to achieve my goal. This is what I want to do.
