(1)表明因變量圖像的對(duì)稱(chēng)性,即表明圖像上大肆點(diǎn)對(duì)于對(duì)稱(chēng)重心(對(duì)稱(chēng)軸)的對(duì)稱(chēng)點(diǎn)仍在圖像上;

(2)表明圖像C1與C2的對(duì)稱(chēng)性,即表明C1上大肆點(diǎn)對(duì)于對(duì)稱(chēng)重心(對(duì)稱(chēng)軸)的對(duì)稱(chēng)點(diǎn)仍在C2上,反之亦然;

(3)弧線(xiàn)C1:f(x,y)=0,對(duì)于y=x+a(y=-x+a)的對(duì)稱(chēng)弧線(xiàn)C2的方程為f(y-a,x+a)=0(或f(-y+a,-x+a)=0);

(4)弧線(xiàn)C1:f(x,y)=0對(duì)于點(diǎn)(a,b)的對(duì)稱(chēng)弧線(xiàn)C2方程為:f(2a-x,2b-y)=0;

(5)若因變量y=f(x)對(duì)x∈R時(shí),f(a+x)=f(a-x)恒創(chuàng)造,則y=f(x)圖像對(duì)于曲線(xiàn)x=a對(duì)稱(chēng);

(6)因變量y=f(x-a)與y=f(b-x)的圖像對(duì)于曲線(xiàn)x=對(duì)稱(chēng);

4.因變量的周期性

(1)y=f(x)對(duì)x∈R時(shí),f(x+a)=f(x-a)或f(x-2a)=f(x)(a>0)恒創(chuàng)造,則y=f(x)是周期為2a的周期因變量;

(2)若y=f(x)是偶因變量,其圖像又對(duì)于曲線(xiàn)x=a對(duì)稱(chēng),則f(x)是周期為2︱a︱的周期因變量;

(3)若y=f(x)奇因變量,其圖像又對(duì)于曲線(xiàn)x=a對(duì)稱(chēng),則f(x)是周期為4︱a︱的周期因變量;

(4)若y=f(x)對(duì)于點(diǎn)(a,0),(b,0)對(duì)稱(chēng),則f(x)是周期為2的周期因變量;
