Dim a(1 To 6) As Integer
Randomize
a(1) = Int(11 * Rnd) + 2
For i = 2 To 6
a(i) = Int(11 * Rnd) + 2
If i Mod 2 = 1 And Not prime(a(i)) Then
i = i - 1
ElseIf Not prime(a(i)) Then
a(i) = a(i) + a(i - 1)
End If
Next i
自定义函数 prime()用于判断参数是否为质数，prime(n) = True 则说明 n 为质数，否则为合数，定义函数代码略，执行该程序后，a(1)～a(6)的值不可能为( )

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
