1、名师精编优秀教案 1.3充分条件、必要条件与命题的四种形式1.3.1推出与充分条件、必要条件(一)一、基础过关1“2x1 或 x0”是“x0”的充分条件B“xy0”是“x0”的必要条件C“|a|b|”是“ab”的充分条件D“|x|1”是“x2不小于 1”的必要条件5设 a，b 为实数，则“0ab1”是“a1a”的()A充分而不必要条件B必要而不充分条件C充分必要条件D既不充分也不必要条件6设 p：x1；q：x1，则 綈 p 是綈 q 的_条件名师精编优秀教案二、能力提升7设 0 x2，则“xsin2x1”是“xsin x1”的()A充分而不必要条件B必要而不充分条件C充分必要条件D既不充分也不

2、必要条件8不等式(ax)(1x)0 成立的一个充分而不必要条件是2x0；q：1x2x60，则 綈 p 是綈 q 的什么条件？12已知 M x|(xa)21，N x|x25x242 910 解(1)因为 a2b20?ab0，ab0D?/a2b20，所以 p 是 q 的充分不必要条件(2)当 p2 或 p2 时，如 p3，则方程x23x 60 无实根，而x2pxp30有实根时，0，得 p2 或 p6，可推出 p2 或 p2.所以 p 是 q 的必要不充分条件(3)若圆 x2 y2 r2与直线 ax byc0 相切，圆心到直线axbyc0 的距离等于r，即 r|c|a2b2，从而 c2(a2b2)r

3、2，反之，也成立所以p 是 q 的充要条件11解p：x2 2x30?x3，綈 p：1x3.q：1x2x60?x3，綈 q：2x3.綈 p?綈 q，但綈 qD?/綈 p，綈 p 是綈 q 的充分不必要条件12 解由(xa)21 得，x22ax(a1)(a1)0，a1xa1.又由 x2 5x240 得 3x8.M 是 N 的充分条件，M?N，a 13a 18，解得 2a7.文档编码:CT3J1Z5A2A2 HX2O4R9H7U3 ZA7F6R8R5L9文档编码:CT3J1Z5A2A2 HX2O4R9H7U3 ZA7F6R8R5L9文档编码:CT3J1Z5A2A2 HX2O4R9H7U3 ZA7F6
