When the door of happiness closes, another opens, but we often look so long at the closed door that we don’t see the one that has been opened for us.
1. Giving someone all your love doesn’t mean that they’ll love you back. Don’t expect love in return. Just wait for it to grow in their hearts.
Dream what you want to dream, go where you want to go, and be what you want to be. Because you have only one life. 2. And it is the only chance for you to do all you want to do.
Don’t let anyone steal your dreams. Follow your heart, no matter what happens.

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
