Verify the identity.cos x- sin x = 1-2 sin 2 xCOSWhich of the following four statements establishes the identity?O A. cos? x- sin?x = (1 - sin?x) – sin?x=1-2 sin2 xX-sinCOSX3DO B.2COSx - sin x= (sin2x+ 1) - sin2x=1-2 sin2 xC. cos2x - sin? x= (sin?x-1) - sin2x=1-2 sin2 xCOSO D.. cos x–sin x= 1= 1-2 sinCOS

The given identity is cos2x-sin2x=1-2sin2x identity used: cos2x+sin2x=1cos2x=1-sin2x

Verify the identity. 2 x- sin2 x= 1-2 sin x cos Which of the following four statements establishes the identity? O A. cos2 x- sin? x= (1- sin?x) - sin?x=1-2 sin2 x O B. cos? x- sin2 x = (sin?x+1) - sin²x=1-2 sin2 x O C. cos? x- sin2 x= (sin2x-1) - sin2x=1-2 sin2 x X = O D. cos2 x- sin² x x = 1= 1-2 sin
