$- \frac{sec^{2}x }{2 \tan (\frac{3}{2} ) x}$

Step-by-step explanation:

use chain rule on

$\frac{d}{dx} \frac{1}{ \sqrt{ \tan\: (x)} }$

Let u = tan x.

Use power rule

$\frac{d}{du} {u}^{n} = nu ^{n - 1}$

$- \frac{1}{2 \tan( \frac{3}{2}x ) } ( \frac{d}{dx} \tan \: (x) )$

Use Trigonometric Differentiation: the derivative of tan x is sec² x.

$- \frac{ \sec^{2} x}{2 \tan( \frac{3}{2} ) x}$
