Best ResponseYou've already chosen the best response.0I just memorized the table the answer is, but it would be nice to know the method to this as it will probably come up on my final \[\sum_{n=0}^{\infty} \frac{(1)^{n}(\pi x)^{2n+1}}{(2n+1)!}\]

Best ResponseYou've already chosen the best response.1so you can put it into the series format pi x  pi^3 (x)^3 + pi^5 (x)^5    ..... 3! 5!
