Summation Question

[missusa]

write out the following sum and compute where possible

\sum 3 x =0 (x2 + 2x + 2)

is that clear???

[malawi_glenn]

do you mean

\sum _{n = .3}(x^2+2x+2) = ?

when x=0

??

Now where is the index n in the expression to be summed over?

And where is your attempt to solution?

[CompuChip]

Malawi that doesn't make much sense either.
Missusa, if you can't write proper LaTeX, it's better to do it completely without. For example, write
"Sum from n = 1 to infinity of (e^(-n / 3) / n^2)"

[Integral]

Maybe OP means:

\sum^3 _{x= 0}(x^2+2x+2)

[HallsofIvy]

write out the following sum and compute where possible

\sum 3 x =0 (x2 + 2x + 2)

is that clear???

Maybe OP means:

\sum^3 _{x= 0}(x^2+2x+2)

Is Integral right about what you mean? Then the sum, from x= 0 to 3 means you replace the "x" in x2+ 2x+ 2 by 0, then by 1, then by 2, then by 3, and add:
(02+ 3(0)+ 2)+ (12+ 2(1)+ 2)+ (22+ 2(2)+ 2)+ (32+ 2(3)+ 2)

[Astronuc]

Maybe OP means:

\sum^3 _{x= 0}(x^2+2x+2) That's about the only way I see it making sense. Same as if the limits of summation were n = 0, 3 and x = n, an integer.

Thank you so much you two are very smart...I do appreciate your help. That is what I meant but I could not write it the way it was.

Thanks again,

Can I get some information about Endogenous Moeny: honrizontalism and structuralism??

[Dick]

Can I get some information about Endogenous Moeny: honrizontalism and structuralism??

Definitely not. Especially if you are talking about Levi-Strauss anthropological structuralism with gratuitous misspellings.

[Astronuc]

Can I get some information about Endogenous Moeny: honrizontalism and structuralism?? That would be better suited in another thread, either in other sciences or in the economic forums.

Ostensibly, such a disussion is found in one's macroeconomic textbook, or one can search on Google with the keywords. Nevertheless -
