do you know the function for this taylor series?

hi all,

I have the function given by taylor series $\sum_{k=0}^\infty \frac{(-1)^k k!}{(2k-1)!} x^k$

anyone knows what this function could be? (or how it can be reduced to any known function)

help would be greatly appreciated...

sum from k = 0 to infinity of (-1)^k*k!*x^k/(2k-1)! - Wolfram|Alpha
