Homework Help: Math

Posted by Anonymous on Sunday, October 31, 2010 at 9:34am.

I have a couple questions about the sums of geometric series.

One. So the formula for the sum is
t(n)=t(1)[(r^n)-1]
But if my series starts at t(0), can I change the formula to
t(n)=t(0)[(r^n)-1]
?

Two. If, in the series, there is a different pattern in the numerator than in the denominator, how can I solve it?
Such as: [x/2]+[(x^2)/4]+[(x^3)/8]...

Thank you.
