Prove that the left side equals the right side:
(sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x

It is proved that the left side equals the right side: (sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x and this will be proved by using the trigonometry properties.

Given :

(sin x)(tan x cos x - cot x cos x) = 1 - 2 cos2x

To prove that the left-hand side equals the right-hand side, take the left-hand part.

Now, write and in the above equation.

Now, further simplify the above eqaution.

Now, apply the property .
