Yuan Longping is China’s “Father of Hybrid Rice (杂交水稻之父)”. He was a great Chinese agricultural (农业) scientist. He worked hard in the field. In 1960, he found a special (特殊的) rice plant. It was a hybrid rice (杂交) plant. It could grow in different places and different kinds of weather.
Zhong Nanshan was born in (出生于) 1936 in Nanjing. In 2020, the virus (病毒) made many people ill. He helped people keep away from (远离) the virus from morning to night. He asked people to stay at home, wash hands often and keep doing exercise every day.

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
