First, multiple-choice questions:
1~5、ABCBD 6~ 10、DCBAC
Second, fill in the blanks:
1 1、 1 12、2 13、5 14、5/7 15、65/24
Third, answer questions:
16 、( 1)P 1=3/6= 1/2，P2 = 3/6 x4/6 = 1/3(2)eξ= 6 1/36
17 、( 1)y？ The asymptote equation of hyperbola m is y = x.
Meanwhile, parabola y? =4x, borrowing points b (4,4) and C (4 4,4).
If D( x, y) is set, | x | "1.
By BD DC = da? =(x- 1)？ +y？ X =- 1/6 ∵| X | "1 ∴ No point D satisfies the meaning of the question.

(2)cosθ=√2 1/7
19, (1)f(x)=6sin(x+π/6) has a monotonic increasing interval of 2Kπ-2/3π, 2kπ+π/3k ∈ z.
(2) The maximum value | AE | is 1+√3/2.
20. When (1) K= 1, the maximum value of f(x) is 0.
(2) Proof (omitted)
2 1, (1) p' = (0,2) (2) (i) The rectangular coordinate equation of circle C is x? +y？ -2x=0
(2) the distance d from the center of the circle c to the straight line l = 3 √ 5/5.
(3) The minimum value of y = f (-x)+f (x+5) is 3.
