∑用于數(shù)學(xué)中表示什么意思

∏是希臘字母，即π的大寫形式，在數(shù)學(xué)中表示求積運算或直積運算，形式上類似于Σ。

符號“∏”是連乘積

比如：∏（下標(biāo)i=1,上標(biāo)n）=1*2*3*4*5*6*……*n

符號“∑”是總和

比如：∑（下標(biāo)i=1,上標(biāo)n）=1+2+3+4+5+6+……+n

擴展資料

大寫Σ用于數(shù)學(xué)上的總和符號，比如：∑Pi，其中i=1,2,...,T，即為求P1 + P2 + ... + PT的和。小寫σ用于統(tǒng)計學(xué)上的標(biāo)準(zhǔn)差。西里爾字母的С及拉丁字母的S都是由Sigma演變而成。

也指求和，這種寫法表示的就是∑j=1+2+3+…+n。

∑符號表示求和，∑讀音為sigma，英文意思為Sum，Summation,就是和。

用∑表示求和的方法叫做Sigma Notation，或∑ Notation。它的小寫是σ，在物理上經(jīng)常用來表示面密度。(相應(yīng)地，ρ表示體密度，η表示線密度)

· 詳解

1、∑符號表示求和，∑讀音為sigma，英文意思為Sum，Summation,就是和。用∑表示求和的方法叫做Singa Notation，或∑ Notation。它的小寫是σ，在物理上經(jīng)常用來表示面密度。(相應(yīng)地，ρ表示體密度，η表示線密度)

2、∑的用法：

n

∑ k i表示下界，n表示上界， k從i開始取數(shù)，一直取到n,全部加起來。

i

∑ i 這樣表達(dá)也可以，表示對i求和，i是變數(shù)

例如：

100

∑ i = 1+2+3+4+5+......+100

i=1

200

∑ i = 5+6+7+8+9+......+200

i=5

500

∑ i;= 10+11+12+13+14+......+500

i=10
