How is your graphic sin/cos table coming? Are you still interested in making one?

Hanno,
The problem with working in minutes of arc is that the Nautical Almanac and charts are in degrees and minutes. Too much trouble to convert to all minutes. I don't think the space savings justifies the extra work. Best not to go too small on print size. Not worth it just to save a page if it is hard to read.
Actually I prefer to work with number tables vs. graduated rules. So the pages of ruled sins, cosines, & haversines is not to be.

Greg,
yet another RIC - this time for Doniol. Clear and to the point.How is your graphic sin/cos table coming? Are you still interested in making one?
It appears my two page cos() list did not find your favor. Could you let me know why?
Is the list too dense or otherwise too difficult to read? What do you think about my proposal to convert all angles to arcmin for simpler calculations by hand - other than doing so is not the tradition?
I would appreciate your comments.
Hanno
