understood?

anonymous · Answer

your a flutterin boss yes. but could you please show the series it can be represented as?

anonymous · Answer

you mean maclaurin's series in general?

anonymous · Answer

like a power series representation

anonymous · Answer

this one?

anonymous · Answer

nono i got this series...

(-1)^n (x^(2n))/2n!

anonymous · Answer

from n=0 to infinty of course

anonymous · Answer

haha sorry... i didn't understand your question earlier about the power series... :)

anonymous · Answer

haha all good, so do i have the right one?

anonymous · Answer

erm I don't think so. am i right?

anonymous · Answer

1 + (-1)^n*(2)^2n-1* (x^(2n))/2n!
where n>0, integer.
am i right?

I got the answer, Thanks alot your a hero no joke
