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 ) : $\dfrac{\cos x}{1 + \sin x}$

Answer 1

Answer:

Step-by-step explanation:

$\dfrac{\cos x}{1 + \sin x}$

माना  कि  $y=\dfrac{\cos x}{1 + \sin x}$

∴ अवकलन करने पर -

$\frac{dy}{dx} =\frac{d}{dx} [\dfrac{\cos x}{1 + \sin x}]\\\\\frac{dy}{dx}=\frac{(1+sinx)\frac{d}{dx}(cosx)-cosx\frac{d}{dx}(1+sinx)}{(1+sinx)^2}\\\\\frac{dy}{dx}=\frac{(1+sinx)(-sinx)-cosx.cosx}{(1+sinx)^2}\\\\\frac{dy}{dx}=\frac{-sinx-sin^2x-cos^2x}{(1+sinx)^2}\\\\\frac{dy}{dx}=\frac{-sinx-(sin^2x+cos^2x)}{(1+sinx)^2}\\\\\frac{dy}{dx}=\frac{-(1+sinx)}{(1+sinx)^2}\\\\\frac{dy}{dx}=\frac{-1}{(1+sinx)}$
