Materi Trigonometri mohon bantuannya ^^ Buktikan bahwa 1/sinx cosx - cos x/sin x = tan x

1 / sin x cos x - cos x/sin x = tan x
(1 - cos^2 x) / sin x cos x = tan x

sin^2 x + cos^2 x = 1
sin^2 x = 1 - cos^2 x

(1 - cos^2 x) / sin x cos x = tan x
sin^2 x / sin x cos x = tan x
sin x sin x / sin x cos x = tan x
sin x / cos x = tan x
tan x = tan x (Terbukti)
