(sin x)(tan x cos x cot x cos x) = 1 2 cos2x [Solved]

sin^2x cos^2 x = 1 2 cos(2x) 2 cos ^2x

Remember
tan(x) = sin(x)/cos(x)
cot(x) = 1/tan(x) = cos(x)/sin(x)
sin^2(x) = 1 cos^2(x)

cot x = 1/(tan x) = (cos x / sin x) => cot x cos x = cos ^2 x / (sin x)

(sin x)(tan x cos x cot x cos x)
= sin(x)(sin(x) cos^2(x)/sin(x))
= sin^2(x) cos^2(x)
= 1 cos^2(x) cos^2(x)
= 1 2 cos2x

0 = -2 cos(2x) 2 cos ^2x

cos(2x) = cos ^2 (x)

cos(2x) = cos ^2 (x)

sin^2x cos^2 x = 1 2 cos(2x) 2 cos ^2x

sin ^2 x cos ^2 x = 1 2 cos (2x)

1 = 1 2 cos(2x) 2 cos ^2x

0 = -2 cos(2x) 2 cos ^2x

so we have

confident, Sin^2x Cos^2 x = a million is real your identify question: Sin^2 x cos x -a million =0 isnt real for all values of x even nevertheless, according to possibility it became a typo yet that may not real reliable success !

cot x = 1/(tan x) = (cos x / sin x) => cot x cos x = cos ^2 x / (sin x)

x = 0 is one solution

sin ^2 x cos ^2 x = 1 2 cos (2x)

x = 0 is one solution
