钩码质量/千克 | 0 | 2 | 4 | 6 |
(1)钩码的质量和弹簧伸长的长度成什么比例关系?
(2)小亮用科技小组制作的这个弹簧秤称一个物体的质量,弹簧的长度是14.8厘米,这个物体的质量是多少千克?

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
