Water is very important too. The scientists say we should drink eight glasses of water every day. Milk and fresh juice are good for our health too, but soft drinks are not good.
Sport is important too. It is fun and can make us stronger and healthier. Riding, swimming, running are all good. Don’t sit in front of the computer or TV for too long. It’s bad for our health.

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
