Bob is verifying the identity, Sine (StartFraction 3 pi Over 2 EndFraction + x) = negative cosine x. He took these steps: Step 1: Sine (StartFraction 3 pi Over 2 EndFraction + x) = sine StartFraction 3 pi Over 2 EndFraction. Cosine x minus cosine StartFraction 3 pi Over 2 EndFraction sine x Step 2: Equals sine StartFraction 3pi Over 2 EndFraction. Cosine x + 0 Step 3: Equals negative 1. cosine x + 0 He made a mistake at which step? Step .
