Question

Пожалуйста решите все и решение распишите подробно (фото пж)

Answer 1

А1
а)Sin11π/3 = Sin(4π - π/3) =- Sin π/3 = - √3/2
б)Cos(-4π/3) = Cos4π/3 = Сos(π + π/3) = -Cosπ/3 = -1/2
в)tg 13π/4 = tg(3π + π/4) = tgπ/4 = 1
г) Sin 29π/3 = Sin(10π - π/3) = Sinπ/3 = √3/2
д)Ctg (-2π/30 = -Ctg2π/3 = -Ctg(π - π/3) = Ctg π/3 = 1/√3
В1 
-Cost·tg t + Sint + tgt = -Sin t + Sin t + tg t = tg t
