$x \in \left(-\frac{\pi}{2}, \frac{\pi}{2}\right)$ के लिए,यदि $y(x) = \int \frac{\operatorname{cosec} x + \sin x}{\operatorname{cosec} x \sec x + \tan x \sin^2 x} \, dx$ और $\lim_{x \rightarrow (\frac{\pi}{2})^-} y(x) = 0$ है,तो $y\left(\frac{\pi}{4}\right)$ का मान ज्ञात कीजिए:

  • A
    $\tan^{-1}\left(\frac{1}{\sqrt{2}}\right)$
  • B
    $-\frac{1}{\sqrt{2}} \tan^{-1}\left(\frac{1}{\sqrt{2}}\right)$
  • C
    $\frac{1}{\sqrt{2}} \tan^{-1}\left(\frac{1}{\sqrt{2}}\right)$
  • D
    $\frac{1}{\sqrt{2}} \tan^{-1}\left(-\frac{1}{2}\right)$
