Question

निम्नलिखित फलनों के अवकलन ज्ञात कीजिए (यह समझा जाय कि a, b, c, d,p, q, r और s निशिचत शून्येतर अचर हैं m तथा n पूर्णांक हैंl ) : $\dfrac{x}{1 + \tan x}$

Answer 1

Answer:

Step-by-step explanation:

माना कि  

            $y=\dfrac{x}{1+tanx} \\\\\dfrac{dy}{dx} =\dfrac{(1+tanx)\dfrac{d}{dx}(x)-x.\dfrac{d}{dx}(1+tanx)}{(1+tanx)^2}\\\\\dfrac{dy}{dx}=\dfrac{(1+tanx)-x.(0+sec^2x)}{(1+tan^x)}\\ \\\dfrac{dy}{dx}=\dfrac{1+tanx-x sec^2x}{(1+tanx)^2}$
