With a lion's strong jaws and claws, it's no wonder that this big cat is a big star in the wild. But the powerful animal still faces dangers-including ones from humans- and their numbers are dropping. That's why this year's Almanac Challenge is all about saving lions—and how you can help. Send in a poster that includes a drawing and a one-sentence message about why it's important to protect lions. You could win a $500 gift card to host a "Lions Forever" party—but you can host one on your own too! Invite friends, family, and classmates to talk about why it's important to save these big cats. And your drawing might be included in a future issue(期) of Nat Geo Kids magazine, Natgeokids.com, or even in next year's Almanac Challenge! |
| Important Entry Information Almanac Challenge starts on May 8, and ends on December 3. Open to U. S. people who are aged 6 to 12 years or older. To enter, visit natgeokids.com/almanac. See official rules for complete prize description and more information. |

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
