Question

(sin x)(tan x cos x - cot x cos x) = 1 - 2 cos^2x
I used Formula: sin^2x+ cos^2x= 1 to make
1 - 2 cos^2 x into sin^2x cos^2x
(sin x)(tan x cos x - cot x cos x) = sin^2x cos^2x
using this formula tan x = sin x/ cos x I plugged it in so now the equation looks like this: (sin x)(sin x cos x - cot x cos x) /cos x = sin^2x cos^2x


Am I doing this correctly? I am so lost please help.

Answer 1

really?? how do I find it?? sorry new to OS

Answer 2

Never mind I think i found it. thank you!
