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 ) : $\dfrac{x^2 \cos(\dfrac{\pi}{4})}{\sin x}$

Answer 1

Answer:

Step-by-step explanation:

$\dfrac{x^2 \cos(\dfrac{\pi}{4})}{\sin x}$

माना कि   $y=\dfrac{x^2 \cos(\dfrac{\pi}{4})}{\sin x}$

या$y=\frac{x^2}{\sqrt{2} sinx}$

अवकलन करने पर -

$\frac{dy}{dx} =\frac{d}{dx} \frac{x^2}{\sqrt{2} sinx}\\\\\frac{dy}{dx}=\frac{\sqrt{2} sinx\frac{d}{dx}(x^2)-x^2\frac{d}{dx}(\sqrt{2}sinx) }{(\sqrt{2}sinx)^2 }\\ \\\frac{dy}{dx}=\frac{\sqrt{2}sinx(2x)-x^2(\sqrt{2} )cosx }{2sin^2x} \\\\\frac{dy}{dx}=\frac{2\sqrt{2}xsinx-\sqrt{2} x^2cosx }{2sin^2x} \\\\\frac{dy}{dx}=\frac{\sqrt{2}.x(2sinx-xcosx) }{2sin^2x}$
