Good readers often use a flowchart（流程图）or webs(网状图）to have better picture of what they read (see the drawing on the right).
A flowchart is used to put events in a certain order. Webs show a main idea and supporting details(细节).
Now try to be a good reader and finish the following TWO tasks.
Task 1: Read Passage l and complete the flowchart.
Task 2: Read Passage2 and complete the webs.
1．①________
2．②________
3．③________

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
