脚和眼睛的争吵
脚对眼睛说:“你高高在上,一点也不着地,我要是不走,你一步都动不了!”眼睛对脚说:“没有我看清道路,你能走吗?”说着就闭上了。脚大步向前走去,因为看不见路,一下子跌倒在刺丛里,脚跌断了,眼睛也被刺伤了。
脚和眼睛争吵时,如果你就在现场,你会怎样劝阻它们?

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
