看图填写下表。
图上距离/cm | 1 | 2 | 3 | 4 | 5 | 6 | 7 | |
实际距离/m |
(2)根据上面的图像,你能说出这幅地图的比例尺是多少吗?图上距离和实际距离成什么比例?为什么?
(3)在这幅地图上,量得甲、乙两地的图上距离是12厘米,两地的实际距离是多少米?

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
