14. The domain of the function is _ _ _ _ _ _ _ _.

15. If known, then = _ _ _ _ _.

16. Simplify.

Three. Solve the problem (74 points for this big question,17-21question, 22 questions 14).

known

Verification:

18. If yes, find the range of angles.

19. The points p and a () on the terminal edge of the angle are symmetrical about the axis, and the points q and a () on the terminal edge of the angle are symmetrical about the straight line. The value.

20. It's called identity. Find the values of a, b and C.

2 1 is known as two roots of the equation, and the terminal edges are perpendicular to each other.

22. Called the third quadrant angle, ask whether there is such a real number m, so that it is the two roots of the equation. If yes, count m realistically; if no, please explain the reason.

Reference answer

I. 1. C2 . D3 . D4 . D5 . C6 . C7 . c8 . C9 . b 10。 C 1 1。 A 12.C。

Two. 13. 14. 15. 16. 1

Three. 17. Because as we all know.

18. Left = right,

19. Because of p (,,,the original formula =- 1-.

20.,

Therefore.

2 1. rule,

In terms of understanding,

22. Suppose there is such a real number m, then

Thirdly, the solution of m=2 or m=

But the sum of 2 does not satisfy the above formula, so such m does not exist.

This is version a.
