x = cos1 a + 2k. tg x = a. x = tg1 a + k. ctg x = a. x = ctg1 a + k. v1.2 by tkr. Osnovne formule iz trigonometrije by ismet-14 in Types > School Work and trigonometrija.
Jun 26, 2015 · Re: Tangens i pretvaranje u sin, cos. A možeš i na ovaj način, bez posmatranja trigonometrijske kružnice, pa kako ti je lakše. sin α = 2 sin α 2cos α 2 = 2 sin α 2 cos α 2tgα 2 ⋅cos2 α 2 = 2tgα 2 ⋅ 1 + cos α 2. tgα 2 ti je zadato, cos α si već izračunao, tako da ti je i jedno i drugo poznato
