Further from the relation (see section N'. 5) 



w -\- X sin 2 «. = T, x= -i 0.00318, 



we deduce -.

and thus : 



sin 3 1^) — 5ÜJ 8 T rrr -\- 0.005 sin x — 0.005 sin 5 t . 



With aid of these formulas we deduce:

Ill connection with this formula, from the table for —* on page 33 

 of the "Investigations", the relation results:
