(2)如图,如果蚂蚁甲从C点出发,沿着C→D→A→E→F→G→A→B→C的路线爬行,1分钟能爬完正方形的一条边;蚂蚁乙从F点出发,沿着F→G→A→B→C→D→A→E→F的路线爬行,2分钟能爬完正方形的一条边.它们同时出发,90分钟后甲、乙分别在什么位置?

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
