K=0 to Infinity Where (-1)^K( X^2K+1). I cant figure out how to the get exponent on X to only be K
Thanks 4 any help!
In fact, you haven't told us what we're supposed to do . . .
I cant figure out how to the get exponent on to only be
. . I don't know what this means . . .
Write out the series: .
We have a geometric series with first term and common ratio
If , the series will converge.
And its sum will be: .
Is that any help?
