(1)若单独由乙队摘果,需要几天才能完成?
(2)若有三种摘果方案,方案1:单独请甲队;方案2:同时请甲、乙两队;方案3:单独请乙队.甲队每摘果一天,需支付给甲队1000元工资,乙队每摘果一天,须支付给乙队1600元工资,你认为用哪种方案完成所有摘果任务需支付给摘果队的总工资最低?最低总工资是多少元?

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
