实验材料:一个底面半径4厘米的圆柱形玻璃杯,1个鸡蛋,1个鸭蛋,水和盐。
实验过程:①往杯子里加水和盐,充分搅拌,测量水面高度;
②放入一个小鸡蛋,鸡蛋沉入杯底,测量水面高度;
③放入一个大鸭蛋,鸭蛋沉入杯底,测量水面高度。
实验记录:
(1)鸡蛋的体积是多少立方厘米?
(2)鸭蛋的体积是120立方厘米,放入鸭蛋后,现在的水面高度是多少厘米?(π取3)

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
