$f(x)=cosh(x)=1+0+\frac{x^2}{2!}+0+\frac{x^4}{4!}+....$ Maclaurin's I'm having some trouble writing this in summation form $\sum_{n=0}^{\infty} \frac{f^(0)}{n!}x^(n)$ I know that: All even #'s can be written as 2n All odd #'s can be written as 2n+1 $\sum_{n=0}^{\infty} \frac{...x^{(2n+1)}}{(2n+1)!}$ I think? so how do I write the $f^n (0)$ correctly?
