Question

The value of $fraction numerator d over denominator d x end fraction open square brackets open parentheses fraction numerator tan squared invisible function application 2 x minus tan squared invisible function application x over denominator 1 minus tan squared invisible function application 2 x tan squared invisible function application x end fraction close parentheses cot invisible function application 3 x close square brackets$ is

$\tan 2 x \tan x$
$\tan 3 x \tan x$
$\sec^{2} x$
$\sec x \tan x$

The correct answer is: $sec squared invisible function application x$

Let, $y equals fraction numerator tan squared invisible function application 2 x minus tan squared invisible function application x over denominator 1 minus tan squared invisible function application 2 x tan squared invisible function application x end fraction$
