(choose chapter or problem)

In Exercises 69-72, identify the two series that are the same.

(a) \(\sum_{n=0}^{\infty} \frac{(-1)^{n}}{(2 n+1) !}\)

(b) \(\sum_{n=1}^{\infty} \frac{(-1)^{n-1}}{(2 n-1) !}\)

(c) \(\sum_{n=1}^{\infty} \frac{(-1)^{n-1}}{(2 n+1) !}\)

Text Transcription:

sum_n=0 ^infty (-1)^n / (2n+1)!

sum_n=1 ^infty (-1)^n-1 / (2n-1)!

sum_n=1 ^infty (-1)^n-1 / (2n+1)!
