数学公试总结（Mathematical public trial summary） The relation between 1. elements and sets 2. De Morgan formula 3. containment relationships 4. exclusion principle The number of subsets of a total of 5. sets; a proper subset - 1; nonempty set - 1; non empty subset - 2. Three forms of analytic expressions of 6., two functions (1) general type; (2) vertex type; (3) zero; 7., the solution of the continuous inequality is often the following form of transformation The 8. equation has only one real root on it and is not equivalent. The former is a necessary but not a sufficient condition of the latter. In particular, the equation has and only has a real root, and is equivalent to, or even, or The maximum value of the two function on 9. closed interval The maximum value of the two function on the closed interval can only be reached at both ends of the interval and the interval, as follows: (1) when a0, if; And... (2) when a0, if, then if, then, then The real root distribution of 10. yuan two equation Basis: if so, the equation has at least one real root in the interval Suppose that (1) the sufficient and necessary condition that the equation has roots in the interval; or; (2) the necessary and sufficient conditions for the existence of the root of the equation in the interval; or; (3) the sufficient and necessary condition that the equation has roots in the interval is or The condition basis for the constant existence of the two inequality with parameter on the 11. definite interval (1) the necessary and sufficient condition for the existence of the two degree inequality (parameter) is constant in the interval (shaped, different) of a given interval (2) on a sub interval of a given interval, the necessary and sufficient condition for the existence of the two degree inequality (parameter) of a parameter is constant (3) the necessary and sufficient condition of constant establishment is or 14., the relationship between the four propositions Original proposition, reciprocal inverse
