(D) આપેલ પદાવલિ: $E = \sin ^4 \frac{\pi}{8} + \cos ^4 \frac{3 \pi}{8} - \sin ^4 \frac{3 \pi}{8} + \sin ^4 \frac{5 \pi}{8} + \cos ^4 \frac{7 \pi}{8} - \sin ^4 \frac{7 \pi}{8}$ $\sin(\pi - 	heta) = \sin 	heta$ અને $\cos(\pi - 	heta) = -\cos 	heta$ નો ઉપયોગ કરતા: $\sin^4 \frac{5 \pi}{8} = \sin^4 \frac{3 \pi}{8}$ $\cos^4 \frac{7 \pi}{8} = \cos^4 \frac{\pi}{8}$ $\sin^4 \frac{7 \pi}{8} = \sin^4 \frac{\pi}{8}$ કિંમતો મૂકતા: $E = \cos ^4 \frac{3 \pi}{8} + \cos ^4 \frac{\pi}{8}$ $\cos^2 	heta = \frac{1 + \cos 2 	heta}{2}$ સૂત્રનો ઉપયોગ કરતા: $E = \frac{3}{4}$

$\sin ^4 \frac{\pi}{8} + \cos ^4 \frac{3 \pi}{8} - \sin ^4 \frac{3 \pi}{8} + \sin ^4 \frac{5 \pi}{8} + \cos ^4 \frac{7 \pi}{8} - \sin ^4 \frac{7 \pi}{8} = ?$
