Mark Quin is trying to make the world happy—one person at a time. He hit upon the idea after studying how a person's happiness could be 1．(影响）by social media(媒体）. Instead of just thinking about his own happiness, he wondered if there was a 2． (秘密的)way to make people around the world happy.
Quin turned to something he 3．(他自己) loves. "All my life I've been taking photos," he says, "and for the past 4．(七) years, I've spent a lot of time making scrapbooks(剪贴簿)filled with photos, 5．（明信片),tickets…It gives me such joy to look back on these. I just thought-maybe I could create an online scrapbook that everyone could 6．(分享）in. "
From his idea came the book The Happiness Scrapbook. Quin travelled in America taking pictures and asking people the 7．(相同的）question: what makes you happy? "I've got photos and answers from strangers, friends, family, as well as others who 8．（清楚地）have something to say," he says.
Quin hopes to start a 9． (网站)or a book, which can be something for people to turn to when they are 10．(充满的）of sadness. That idea makes me more than just happy," says Quin.

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
