geometrical progression
Hi there , i've a question , how can i do a geometrical or arithmetical
progression in one function at one cell in excel as example this series ˆ‘_(i=0)^n–’〖xi〗^2 ˆ¶xi=x(i-1)+ 1 and other similar series and that function request x when i = o and n and thanks |
geometrical progression
Assume you want to add up
5/1! +( 5^2)/2! + (5^3)/3! + (5^4)/4! use =SUMPRODUCT(5^(ROW(1:4))/FACT(ROW(1:4))) follow evaluate formula and watch how the calculation works - that will help Modify to suit your needs -- Wag more, bark less "arithmatical and geometrical series" wrote: Hi there , i've a question , how can i do a geometrical or arithmetical progression in one function at one cell in excel as example this series ˆ‘_(i=0)^n–’〖xi〗^2 ˆ¶xi=x(i-1)+ 1 and other similar series and that function request x when i = o and n and thanks |
geometrical progression
=SUMPRODUCT(5^(ROW(1:4))/FACT(ROW(1:4)))
Hi. This returns 64.375 Ont sure if that's what the op wants, but just to mention one of a few other ways for the above ... =SERIESSUM(5,1,1,1/FACT(ROW(1:4))) 'or =SERIESSUM(5,1,1,1/{1,2,6,24}) also returns 64.375 = = = = = HTH Dana DeLouis On 3/17/2010 11:41 AM, Brad wrote: Assume you want to add up 5/1! +( 5^2)/2! + (5^3)/3! + (5^4)/4! use =SUMPRODUCT(5^(ROW(1:4))/FACT(ROW(1:4))) follow evaluate formula and watch how the calculation works - that will help Modify to suit your needs |
