From: Shyamal Kumar Das To: Doctor Nisith Bairagi Sir, Thanks for your letter post on 02032013 congratulating and seconding my method on Nsection of angle. I have given a generalized formula which most probably missed your attention. I am now making copypaste from my original writeup dt. 09092011 and posted in Math. Forum on 10092011, which is as follows: Remarks: To get best and accurate result, ? /e*n should be equal to 4.5degree ( Magic value ). Here, ? is the given angle, ?e? is the no of bisected portions, i.e. 2, 4, 8, or 16 and ?n? is the no. of divisions. This Magic value, as calculation reveals , is that angle when subtended at the centre by an arc , the chord length and arc length are almost equal. Also, note that, no. of graduations taken at a time = no of bisected portions i.e., 2,4,8 or 16. Regards.
