∑用于數學(xué)中表示什么意思

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

符號“∏”是連乘積

比如：∏（下標i=1,上標n）=1*2*3*4*5*6*……*n

符號“∑”是總和

比如：∑（下標i=1,上標n）=1+2+3+4+5+6+……+n

擴展資料

大寫(xiě)Σ用于數學(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(xiě)σ用于統計學(xué)上的標準差。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(xiě)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(xiě)是σ，在物理上經(jīng)常用來(lái)表示面密度。(相應地，ρ表示體密度，η表示線(xiàn)密度)

∑ i = 1+2+3+4+5+......+100

i=1

200

∑ i = 5+6+7+8+9+......+200

i=5
