sin(e^-k)

I'm not sure where to start..

**drwls**, Wednesday, February 27, 2008 at 3:06amAs k becomes large, e^-k becomes much less than 1, and sin(e^-k) approaches e^-k

The sum of the series 1 + 1/e + 1/e^2 converges to

1 /(1 - 1/e)= 1.582

High-order terms of the series

sin(e^-k) will behave similarly, but the sum of the entire series will be somethat less than 1.582.
