page note 235 * x sec ½ (B-C) in most cases gives a more accurate result a than y cosec ½ (B-C).

page note 235 ‡ Further notes to the examples:
-
(i) All angles used in the evaluation are acute.
-
(ii) if, as can easily happen in the tangent formula, the angles to be found get interchanged, by using ½ (B-C) in cases where it should be ½(C-B, the error is at once shown up by the check.
