Cosec 30 – Latihan 8.2, 1 Evaluasi berikut ini: (iii) “cos 45” / “sec 30 + cosec 30” “cos 45” = 1/2 “sec 30” = 1/(cos 30) = 1/(3/2) = 2/3 jadi cos 45 / (detik 30 + 30) = (1/2) / ((3/3 + 2/1)) = 1/2 1/2 / ((2/3 + 2) / 1 )) = 1/2 1/2 / ((2 1 + 2 3) / (3 1)) = 1/2 (3 1) / ((2 1 + 2 3)) = 1/2 3 / ( ( ( 2 + 2 3)) = (1 3) / (2 2 (1 + 3)) = 3 / (2 2 (1 + 3)) = 3 / (2 2 (3 + 1)) rasionalisasi = ( 3 (3 1)) / (2 2 (3 + 1) (3 1)) = (3 3) / (2 2 ((3) 2 12)) = (3 3) / (2 2 (3 1) ) = (3 3) /.
