春天来了,我们带领林老师到郊外活动。我们沿着弯弯的小路走着,不一会儿,巍峨的山峰、美丽的田野、弯弯曲曲的小溪,便呈现在我们眼前。看,百灵鸟在枝头快活地歌唱;听,美丽的蝴蝶在花从中翩翩起舞。大家都沉醉在迷人的春色中。

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
