Penjelasan dengan langkah-langkah:
Cos x /cot^2 2x
= cos x / cos^2x/sin^2x
= sin ^2 x.cos x /cos^2x
= sin^2 x. / cos x
= sin x. Sin x/cos x
= sin x. Tan x
^ artinya pangkat

Cos x /cot^2 2x
= cos x / cos^2x/sin^2x
= sin ^2 x.cos x /cos^2x
= sin^2 x. / cos x
= sin x. Sin x/cos x
= sin x. Tan x
^ artinya pangkat
= cos x / (cos² x) / (sin² x)
= cos x . sin²x / cos² x
= sin² x / cos x
= sin x. sin x / cos x
= sin x . tan x
