Raise ( (sin)(x)) to the power of ( 1). ( ((sin))^1(x)(sin)(x)(cos)(x)) Raise ( (sin)(x)) to the power of ( 1). ( ((sin))^1(x)((sin))^1(x)(cos)(x)) Use the power rule ( a^ma^n=a^(m+n)) to combineexponents. ( ((sin)(x))^(1+1)...
\sin54^\circ-\sin18^\circ=2\cos36^\circ\cdot \sin 18^\circ=2\frac{\cos36^\circ\cdot \sin 18^\circ\cdot \cos 18^\circ}{\cos18^\circ}=2\frac{\frac{1}{4}\sin 72^\circ}{\cos 18^\circ}=\frac{1}{2} 于是, \sin ^{2} 54^{\circ}+\sin ^{2} 18^{\circ}=(\sin...
