根据提示写一封60~80字的信。
Tom 邀请Li Ping 参加他这周日的生日宴会,但Li Ping的父母出差要到下个月回来,奶奶又卧病在床,需要人照顾。再说英语考试即将来临,因此,无法前去参加生日宴会。Li Ping感到很抱歉,只好写信辞谢。
Dear Tom,
Thank you very much for inviting me to your birthday party. I'd love to go but I can't.
My parents…

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
