**New Problem:**

**A point is created at the origin and labeled O. A prime number p is picked and 2 points are created at (p,0) and (-p,0). The points are labeled B and C. Using OB and OC as the bottoms, two 5 sided regular polygons are created. They are blue in the diagram. The orange area represents the overlap between the two polygons.**

**What is the value of the Area of polygon OBGHI divided by the area of the orange polygon?**

**A says) All geometry ended when the big boys like me got into it and converted it into topology. The answer is obviously 5.**

**B says) That ain't right. Even a bumpkin knows the answer ain't 5.**

**C says) A sure is fast and accurate too. A, do you train people and what do you charge?**

**D says) What are we talking about? I got 5.000000000000000000000000000000000000000000000000000000000001 so the answer is close to 5 but not 5.**

**E says) I am not sure about the bumpkin remark but the answer has a radical in it.**

**A says) E, you would do well to take some lessons from me instead of listening to that bumpkin over there.**

**A wild brawl ensues and we have no interest in it. The question remains... can you find the answer?**

No probs. Just don't strain anything...except maybe the tea leaves during a cuppa break.

RootApproximant with FullSimplify, to convert the G result to that nice, brief, accurate answer.

I had tried that with Rationalize in M with G's CAS results but of course only got a fraction.

You could have even done this "closed form 4.73606797749979" at Alpha!

Sorry...I'm not familiar with the term 'closed form'. I'll try to remember that.

It means expressing something in elementary forms. Shorthand for a few simple, common operations like sqrt, +, -, / , *, a power or a trig term.

Thanks, I think I understand.

I thought that my M would be able to do all of what Alpha could, but obviously not, seeing that A made that interpretation...which I can't get my M to do.

The language they have written for Wolfram is a trade secret. I have emailed them to put it into the future M's but Stephen can be a bit stubborn.
