Verify the identity. sint- cos t=2 sin t-1 Which of the following four statements establishes the identity? O A. sin t- cos* t= (sin? t- cos? t) (sin?t- cos? t) = 2 sin? t-1 ,??- cos² 1) = 2 sint- cos O B. 4. si n* t- cos* t= (cost) (sin? t+ cos t) = 2 sin? t- 1 Oc. O C. sin t- cos t= 4. (sin t+ cos? t) (sin? t- cos? t) = 2 sin? t-1 OD. sin“ t- cos t= (sin²t) (sint+ cost) = 2 sin t-1
