Manipulating the left-hand side of the given equation, 
$$\cos x + \sin x \tan x = \cos x + \frac{\sin^2 x}{\cos x} = \frac{\cos^2 x}{\cos x} + \frac{\sin^2 x}{\cos x} = \frac{\cos^2 x + \sin^2 x}{\cos x} = \frac{1}{\cos x} = \sec x.$$ 
Therefore, the given equation is false.

cos⁡x+sin⁡xtan⁡x=csc⁡x\cos x + \sin x \tan x = \csc xcosx+sinxtanx=cscx

$\cos x + \sin x \tan x = \csc x$
