You can put this solution on YOUR website!
Sigma sec(2^r theta)?

Hmmm!  Was it something like this:

sum%28sec%282%5Er%29phi%2C+r=0%2C+infinity+%29

(I can't make a "theta", so I made a "phi" instead.)
Was there something below the "sigma" and something
above it?  Please repost telling us more about the problem. 
We can't answer it from just what you have given us.
