sin 600° cos 1.410 + cosec 1.200° cotan 570°

Halo Nyimas, kakak bantu jawab ya. Jawaban: 5/4. Konsep: sin (a+k.360°) = sin a cos (a+ k.360°) = cos a cosec (a + k.360°) = cosec a cotan (a + k.180°) = cotan a Pembahasan: sin 600° cos 1.410° + cosec 1.200° cotan 570° =sin (240°+(1)(360°)) cos (330°+(3)(360°)) + cosec (120°+(3)(360°)) cotan (30°+(3)(180°)) =sin 240° cos 330° + cosec 120° cotan 30° =-((√3)/2)((√3)/2) + ((2√3)/3))(√3) =-(3/4) + (6/3) = -(9/12) + (24/12) = 15/12 =5/4 Jadi, hasil dari sin 600° cos 1.410° + cosec 1.200° cotan 570° adalah 5/4. Semoga membantu ya.
