高一數(shù)學(xué)必修一知識(shí)點(diǎn)總結(jié)
第一章集合與函數(shù)概念
一、集合有關(guān)概念
1.集合的含義
2.集合的中元素的三個(gè)特性:
(1)元素的確定性如:世界上最高的山
(2)元素的互異性如:由HAPPY的字母組成的集合{H,A,P,Y}
(3)元素的無(wú)序性:如:{a,b,c}和{a,c,b}是表示同一個(gè)集合
3.集合的表示:{…}如:{我校的籃球隊(duì)員},{太平洋,大西洋,印度洋,北冰洋}
(1)用拉丁字母表示集合:A={我校的籃球隊(duì)員},B={1,2,3,4,5}
(2)集合的表示方法:列舉法與描述法。
注意:常用數(shù)集及其記法:
非負(fù)整數(shù)集(即自然數(shù)集)記作:N
正整數(shù)集:N*或N+
整數(shù)集:Z
有理數(shù)集:Q
實(shí)數(shù)集:R
1)列舉法:{a,b,c……}
2)描述法:將集合中的元素的公共屬性描述出來,寫在大括號(hào)內(nèi)表示集合{xR|x-32},{x|x-32}
3)語(yǔ)言描述法:例:{不是直角三角形的三角形}
4)Venn圖:
4、集合的分類:
(1)有限集含有有限個(gè)元素的集合
(2)無(wú)限集含有無(wú)限個(gè)元素的集合
(3)空集不含任何元素的集合例:{x|x2=-5}
二、集合間的基本關(guān)系
1.“包含”關(guān)系—子集
注意:有兩種可能(1)A是B的一部分,;(2)A與B是同一集合。
反之:集合A不包含于集合B,或集合B不包含集合A,記作AB或BA
2.“相等”關(guān)系:A=B(5≥5,且5≤5,則5=5)
實(shí)例:設(shè)A={x|x2-1=0}B={-1,1}“元素相同則兩集合相等”
即:①任何一個(gè)集合是它本身的子集。AA
②真子集:如果AB,且AB那就說集合A是集合B的真子集,記作AB(或BA)
③如果AB,BC,那么AC
④如果AB同時(shí)BA那么A=B
3.不含任何元素的集合叫做空集,記為Φ
規(guī)定:空集是任何集合的子集,空集是任何非空集合的真子集。
4.子集個(gè)數(shù):
有n個(gè)元素的集合,含有2n個(gè)子集,2n-1個(gè)真子集,含有2n-1個(gè)非空子集,含有2n-1個(gè)非空真子集
三、集合的運(yùn)算
運(yùn)算類型交集并集補(bǔ)集
定義由所有屬于A且屬于B的元素所組成的集合,叫做A,B的交集.記作AB(讀作‘A交B’),即AB={x|xA,且xB}.
由所有屬于集合A或?qū)儆诩螧的元素所組成的集合,叫做A,B的并集.記作:AB(讀作‘A并B’),即AB={x|xA,或xB}).
設(shè)S是一個(gè)集合,A是S的一個(gè)子集,由S中所有不屬于A的元素組成的集合,叫做S中子集A的補(bǔ)集(或余集)
記作,即
CSA=
韋
恩
圖
示
性
質(zhì)AA=A
AΦ=Φ
AB=BA
ABA
ABB
AA=A
AΦ=A
AB=BA
ABA
ABB
(CuA)(CuB)
=Cu(AB)
(CuA)(CuB)
=Cu(AB)
A(CuA)=U
A(CuA)=Φ.
二、函數(shù)的有關(guān)概念
1.函數(shù)的概念
設(shè)A、B是非空的數(shù)集,如果按照某個(gè)確定的對(duì)應(yīng)關(guān)系f,使對(duì)于集合A中的任意一個(gè)數(shù)x,在集合B中都有唯一確定的數(shù)f(x)和它對(duì)應(yīng),那么就稱f:A→B為從集合A到集合B的一個(gè)函數(shù).記作:y=f(x),x∈A.其中,x叫做自變量,x的取值范圍A叫做函數(shù)的定義域;與x的值相對(duì)應(yīng)的y值叫做函數(shù)值,函數(shù)值的集合{f(x)|x∈A}叫做函數(shù)的值域.
注意:
1.定義域:能使函數(shù)式有意義的實(shí)數(shù)x的集合稱為函數(shù)的定義域。
求函數(shù)的定義域時(shí)列不等式組的主要依據(jù)是:
(1)分式的分母不等于零;
(2)偶次方根的被開方數(shù)不小于零;
(3)對(duì)數(shù)式的真數(shù)必須大于零;
(4)指數(shù)、對(duì)數(shù)式的底必須大于零且不等于1.
(5)如果函數(shù)是由一些基本函數(shù)通過四則運(yùn)算結(jié)合而成的.那么,它的定義域是使各部分都有意義的x的值組成的集合.
(6)指數(shù)為零底不可以等于零,
(7)實(shí)際問題中的函數(shù)的定義域還要保證實(shí)際問題有意義.
相同函數(shù)的判斷方法:①表達(dá)式相同(與表示自變量和函數(shù)值的字母無(wú)關(guān));
②定義域一致(兩點(diǎn)必須同時(shí)具備)
2.值域:先考慮其定義域
(1)觀察法(2)配方法(3)代換法
3.函數(shù)圖象知識(shí)歸納
(1)定義:
在平面直角坐標(biāo)系中,以函數(shù)y=f(x),(x∈A)中的x為橫坐標(biāo),函數(shù)值y為縱坐標(biāo)的點(diǎn)P(x,y)的集合C,叫做函數(shù)y=f(x),(x∈A)的圖象.C上每一點(diǎn)的坐標(biāo)(x,y)均滿足函數(shù)關(guān)系y=f(x),反過來,以滿足y=f(x)的每一組有序?qū)崝?shù)對(duì)x、y為坐標(biāo)的點(diǎn)(x,y),均在C上.
(2)畫法
1.描點(diǎn)法:2.圖象變換法:常用變換方法有三種:1)平移變換2)伸縮變換3)對(duì)稱變換
4.區(qū)間的概念
(1)區(qū)間的分類:開區(qū)間、閉區(qū)間、半開半閉區(qū)間(2)無(wú)窮區(qū)間(3)區(qū)間的數(shù)軸表示.
5.映射
一般地,設(shè)A、B是兩個(gè)非空的集合,如果按某一個(gè)確定的對(duì)應(yīng)法則f,使對(duì)于集合A中的任意一個(gè)元素x,在集合B中都有唯一確定的元素y與之對(duì)應(yīng),那么就稱對(duì)應(yīng)f:AB為從集合A到集合B的一個(gè)映射。記作“f(對(duì)應(yīng)關(guān)系):A(原象)B(象)”
對(duì)于映射f:A→B來說,則應(yīng)滿足:
(1)集合A中的每一個(gè)元素,在集合B中都有象,并且象是唯一的;
(2)集合A中不同的元素,在集合B中對(duì)應(yīng)的象可以是同一個(gè);
(3)不要求集合B中的每一個(gè)元素在集合A中都有原象。
6.分段函數(shù)
(1)在定義域的不同部分上有不同的解析表達(dá)式的函數(shù)。
(2)各部分的自變量的取值情況.
(3)分段函數(shù)的定義域是各段定義域的交集,值域是各段值域的并集.
補(bǔ)充:復(fù)合函數(shù)
如果y=f(u)(u∈M),u=g(x)(x∈A),則y=f[g(x)]=F(x)(x∈A)稱為f、g的復(fù)合函數(shù)。
二.函數(shù)的性質(zhì)
1.函數(shù)的單調(diào)性(局部性質(zhì))
(1)增函數(shù)
設(shè)函數(shù)y=f(x)的定義域?yàn)镮,如果對(duì)于定義域I內(nèi)的某個(gè)區(qū)間D內(nèi)的任意兩個(gè)自變量x1,x2,當(dāng)x1x2時(shí),都有f(x1)f(x2),那么就說f(x)在區(qū)間D上是增函數(shù).區(qū)間D稱為y=f(x)的單調(diào)增區(qū)間.
如果對(duì)于區(qū)間D上的任意兩個(gè)自變量的值x1,x2,當(dāng)x1x2時(shí),都有f(x1)>f(x2),那么就說f(x)在這個(gè)區(qū)間上是減函數(shù).區(qū)間D稱為y=f(x)的單調(diào)減區(qū)間.
注意:函數(shù)的單調(diào)性是函數(shù)的局部性質(zhì);
(2)圖象的特點(diǎn)
如果函數(shù)y=f(x)在某個(gè)區(qū)間是增函數(shù)或減函數(shù),那么說函數(shù)y=f(x)在這一區(qū)間上具有(嚴(yán)格的)單調(diào)性,在單調(diào)區(qū)間上增函數(shù)的圖象從左到右是上升的,減函數(shù)的圖象從左到右是下降的.
(3).函數(shù)單調(diào)區(qū)間與單調(diào)性的判定方法
(A)定義法:
(1)任取x1,x2∈D,且x1x2;
(2)作差f(x1)-f(x2);或者做商
(3)變形(通常是因式分解和配方);
(4)定號(hào)(即判斷差f(x1)-f(x2)的正負(fù));
(5)下結(jié)論(指出函數(shù)f(x)在給定的區(qū)間D上的單調(diào)性).
(B)圖象法(從圖象上看升降)
(C)復(fù)合函數(shù)的單調(diào)性
復(fù)合函數(shù)f[g(x)]的單調(diào)性與構(gòu)成它的函數(shù)u=g(x),y=f(u)的單調(diào)性密切相關(guān),其規(guī)律:“同增異減”
注意:函數(shù)的單調(diào)區(qū)間只能是其定義域的子區(qū)間,不能把單調(diào)性相同的區(qū)間和在一起寫成其并集.
8.函數(shù)的奇偶性(整體性質(zhì))
(1)偶函數(shù):一般地,對(duì)于函數(shù)f(x)的定義域內(nèi)的任意一個(gè)x,都有f(-x)=f(x),那么f(x)就叫做偶函數(shù).
(2)奇函數(shù):一般地,對(duì)于函數(shù)f(x)的定義域內(nèi)的任意一個(gè)x,都有f(-x)=—f(x),那么f(x)就叫做奇函數(shù).
(3)具有奇偶性的函數(shù)的圖象的特征:偶函數(shù)的圖象關(guān)于y軸對(duì)稱;奇函數(shù)的圖象關(guān)于原點(diǎn)對(duì)稱.
9.利用定義判斷函數(shù)奇偶性的步驟:
○1首先確定函數(shù)的定義域,并判斷其是否關(guān)于原點(diǎn)對(duì)稱;
○2確定f(-x)與f(x)的關(guān)系;
○3作出相應(yīng)結(jié)論:若f(-x)=f(x)或f(-x)-f(x)=0,則f(x)是偶函數(shù);若f(-x)=-f(x)或f(-x)+f(x)=0,則f(x)是奇函數(shù).
注意:函數(shù)定義域關(guān)于原點(diǎn)對(duì)稱是函數(shù)具有奇偶性的必要條件.首先看函數(shù)的定義域是否關(guān)于原點(diǎn)對(duì)稱,若不對(duì)稱則函數(shù)是非奇非偶函數(shù).若對(duì)稱,(1)再根據(jù)定義判定;(2)由f(-x)±f(x)=0或f(x)/f(-x)=±1來判定;(3)利用定理,或借助函數(shù)的圖象判定.
10、函數(shù)的解析表達(dá)式
(1)函數(shù)的解析式是函數(shù)的一種表示方法,要求兩個(gè)變量之間的函數(shù)關(guān)系時(shí),一是要求出它們之間的對(duì)應(yīng)法則,二是要求出函數(shù)的定義域.
(2)求函數(shù)的解析式的主要方法有:1.湊配法2.待定系數(shù)法3.換元法4.消參法
11.函數(shù)最大(?。┲?br>
○1利用二次函數(shù)的性質(zhì)(配方法)求函數(shù)的最大(?。┲?br>
○2利用圖象求函數(shù)的最大(?。┲?br>
○3利用函數(shù)單調(diào)性的判斷函數(shù)的最大(小)值:
如果函數(shù)y=f(x)在區(qū)間[a,b]上單調(diào)遞增,在區(qū)間[b,c]上單調(diào)遞減則函數(shù)y=f(x)在x=b處有最大值f(b);
如果函數(shù)y=f(x)在區(qū)間[a,b]上單調(diào)遞減,在區(qū)間[b,c]上單調(diào)遞增則函數(shù)y=f(x)在x=b處有最小值f(b);

第四章函數(shù)的應(yīng)用
一、方程的根與函數(shù)的零點(diǎn)
1、函數(shù)零點(diǎn)的概念:對(duì)于函數(shù),把使成立的實(shí)數(shù)叫做函數(shù)的零點(diǎn)。
2、函數(shù)零點(diǎn)的意義:函數(shù)的零點(diǎn)就是方程實(shí)數(shù)根,亦即函數(shù)的圖象與軸交點(diǎn)的橫坐標(biāo)。
