(D) ત્રિકોણમિતીય નિત્યસમનો ઉપયોગ કરતા:$1$. $	an(x - \frac{\pi}{2}) = -\cot x$$2$. $\cos(\frac{3\pi}{2} + x) = \sin x$$3$. $\sin(\frac{7\pi}{2} - x) = -\cos x$$4$. $\cos(x - \frac{\pi}{2}) = \sin x$$5$. $	an(\frac{3\pi}{2} + x) = -\cot x$આ કિંમતો પદાવલિમાં મૂકતા:અંશ: $(-\cot x)(\sin x) - (-\cos x)^3 = -\cos x + \cos^3 x = \cos x(\cos^2 x - 1) = -\cos x \sin^2 x$છેદ: $(\sin x)(-\cot x) = -\cos x$પદાવલિ: $\frac{-\cos x \sin^2 x}{-\cos x} = \sin^2 x$.

પદાવલિ $\frac{\tan(x - \frac{\pi}{2}) \cdot \cos(\frac{3\pi}{2} + x) - \sin^3(\frac{7\pi}{2} - x)}{\cos(x - \frac{\pi}{2}) \cdot \tan(\frac{3\pi}{2} + x)}$ નું સાદું રૂપ આપતા શું મળે?
