SOLUTION: can you please prove this identity (tan x - cot x) / (tan^2 x - cot^2 x)= sin x cos x
You can put this solution on YOUR website! (tan x - cot x) / (tan^2 x - cot^2 x)= sin x cos x.. start with left side (tan x - cot x) / (tan^2 x - cot^2 x) difference of squares (tan x - cot x) / (tan x - cot x)(tan x + cot x) 1/(tan x + cot x) 1/((sinx/co...
