Homework Statement
I seem to have forgotten how to express a series as a function. I took calc 2 over the summer so we rushed through everything and i don't think all that information got a chance to settle. So here is the question. I'm going to try using syntax but i will write it out as well as this is the first time i use syntax.
If
[tex]\sum \frac{x^{2n}}{n!}[/tex] = f(x) , then express f in terms of standard functions.
sum (n=0 to infinity) of (x^(2n)) / (n!)
