| I created Teens Helping Seniors with my friends. The group has about 200 volunteers. The volunteers deliver food or other supplies for the elderly in town. I spend six to eight hours a week buying food and making deliveries. By now we have completed 350 deliveries. | ||

| I organized Mittler Senior Technology, a program to help the elderly learn how to use computers and smartphones. Now there are 50 local seniors in the weekly technology classes. I want to make sure that the seniors could stay connected to the world. | ||

| I came up with a way to help lonely seniors with my friends. We call it the Joy 4 All Project. By dialing 569-4255, the elderly can hear pre-recorded jokes and poems. The hotline has received more than 1, 800 phone calls. | ||

| I heard that the seniors in the nursing home couldn’t see their families and friends very often, so my friends and I decided to cheer up the elderly by writing them letters. We want them to know that nobody is being forgotten. By now more than 100 students in my school have joined us. | ||

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
