(1)求该园圃栽种的花卉总株数关于的函数表达式;
(2)若三种花卉共栽种6600株,则A,B,C三个区域的面积分别是多少?
(3)已知三种花卉的单价(都是整数)之和为45元,且差价均不超过10元,在(2)的前提下,全部栽种共需84000元,请写出甲、乙、丙三种花卉中,种植面积最大的花卉总价.

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
