I lost my pencil box this morning. I put it in my desk. It’s blue and black. The picture on it is a toy car. It’s new. There is a red pen, two pencils, two rulers, three erasers and three candies in it. I like it very much. Can you help me find it?

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
