(D) Given: $m = 	an 	heta + \sin 	heta$ and $n = 	an 	heta - \sin 	heta$.Calculate $m^2 - n^2$:$m^2 - n^2 = (m + n)(m - n)$$m + n = (	an 	heta + \sin 	heta) + (	an 	heta - \sin 	heta) = 2 	an 	heta$$m - n = (	an 	heta + \sin 	heta) - (	an 	heta - \sin 	heta) = 2 \sin 	heta$$m^2 - n^2 = (2 	an 	heta)(2 \sin 	heta) = 4 	an 	heta \sin 	heta$ ... $(i)$Calculate $4\sqrt{mn}$:$mn = (	an 	heta + \sin 	heta)(	an 	heta - \sin 	heta) = 	an^2 	heta - \sin^2 	heta$$mn = \frac{\sin^2 	heta}{\cos^2 	heta} - \sin^2 	heta = \sin^2 	heta \left( \frac{1}{\cos^2 	heta} - 1 ight) = \sin^2 	heta \left( \frac{1 - \cos^2 	heta}{\cos^2 	heta} ight) = \sin^2 	heta \frac{\sin^2 	heta}{\cos^2 	heta} = \sin^2 	heta 	an^2 	heta$$\sqrt{mn} = \sqrt{\sin^2 	heta 	an^2 	heta} = \sin 	heta 	an 	heta$$4\sqrt{mn} = 4 \sin 	heta 	an 	heta$ ... $(ii)$From $(i)$ and $(ii)$,we get ${m^2} - {n^2} = 4\sqrt {mn}$.
