RE: Small challenge
I arrived at a slightly different results:
Δ ≈ 6.52° = interior angle formed by the line segments BOD (½ the central angle of the sector formed by COD) θ ≈ 23.58° = interior angle formed by line segments ADO D ≈ (0.118474, 0.993725) D ≈ (0.111847, 0.993725) typo correction verified by WolframAlpha & AnalyzeMath AD ≈ 0.22710 = d = a*R AD ≈ 0.22369 = d = a*R correction for typo [attachment=4914] [attachment=4915] The difference seems to be associated with the assumption guiding the calculation of the distance EB. I do not see how the Arc Segment S for the sector CAD with a central angle anchored to point A and the Arc Segment for the sector COD with a central angle anchored at point O can both describe the same arc segment CBD. Although the difference of the sagitta calculated this way may be small, in a manner similar to the small difference between the SIN & the TAN of a small angle, I take exception to the equality of the results, not the equivalency. Where am I going wrong? BEST! SlideRule |
