y'+xy=0 when y(0)=1

Write the solution in the form of a power series and then recognize what function it represents.

************************************

My answer:

[tex]\sum[/tex](-1)

^{k}*[(x

^{2k})/(2

^{k})*k!]

Is my answer correct?

Is it written in the form of a power series?

What function does it represent?

Thanks to anyone that helps!
