E=2=[(2xB)/2] +a+b

E is Epsolon symbol
B is Beta symbol


It was on Treasure map from 1800's LOOK UPPER left corner area

is this the best scan you have? To me, i wouldn't say that's what the equation seems to say.

but:
\epsilon=2=\frac{2\beta}2 + a + b

this wouldn't make much sense because 2B/2=B so the 2s are irrelevant.
the equation is so simple that it could very well relate to anything. Epsilon and beta are not normally associated with maps or direction finding as far as I can tell. Provide more info if you have it.

I'm sorry, I wrote equation wrong as you can see on map it should be

E=2=[(nxB)/2]+a+b E is Epsilon, B is Beta

farther over to right on map you can see what appears to be " c-d"
Don't know if that is part of it or just separate item.

so you've got:
\epsilon=2=\frac{nx\beta}2+a+b
is the x a variable or just multiplication? Maybe you can't tell. You can't get a better scan of that area for us to review? This equation still isn't looking like anything that is standard. From the looks of your image it's intended to be a reminder to the original creator of the map of some detail that will lead to the "treasure". Are there any other epsilons or betas on the map that you can see?

It appears on close up to be "n x B" where ''x'' is a DOT.

Sorry. It's still not ringing a bell! I'll continue pondering it but please try to post a higher resolution scan.

I am afraid a bigger scan will not show any more than the pic posted.

Below the equation it looks like some sort of orbit, therefore I am led to believe that the epsilon may stand for eccentricity (of an elipse). However I am not familiar with the formula either. Is a, b, beta or epsilon marked anywhere on the document?

good point! The OP can view http://en.wikipedia.org/wiki/Kepler's_laws_of_planetary_motion for a number of orbital equations that involve epsilon, a, b... but I don't see any beta anywhere.
