Jawab:
trigonometri
tan x = sin x / cos x
Penjelasan dengan langkah-langkah:
tan x - 3 sin² x = 0
(sin x )/ (cos x ) - 3 sin² x = 0
sin x ( 1/cos x - 3 sin x ) = 0
pembuat nol fungsi
sin x = 0 atau 1/cos x - 3 sin x = 0
..
i) sin x = 0
ii) 1/cos x - 3 sin x = 0
1/cos x = 3 sin x
3 sin x cos x = 1
sin x cos x = 1/3
