What could be the next step when verifying the following:
 $\frac{\left(\tan x-\cot x\right)}{\sin x\cos}$  

•  $\frac{\tan x}{\sin x}-\frac{\cot x}{\cos x}$  

•  $\frac{\left(\tan x-\cot x\right)}{\sin x}-\frac{\left(\tan x-\cot x\right)}{\cos x}$  

•  $\frac{\tan x}{\sin x\cos x}-\frac{\cot x}{\sin x\cos x}$  

•  $\frac{1}{\sin x\cos x}$
