Hi Martin,
What Derive 6.10 does on these ?
Thanks, Alex
 1. WolframAlpha doesn't give more digits on calculating sum(1/(exp(1)^(Pi*sqrt(1/2*(1+sqrt(2*n+1))))),n=0...infinity)
It only gives 0.2549971272923126
PARI gives gp > suminf(n=0,1/(exp(1)^(Pi*sqrt(1/2*(1+sqrt(2*n+1)))))) %1 = 0.2549971273049976427477869494
2. WolframAlpha doesn't process 4*sum(1/((log(Pi))^n*(exp(1)^(Pi*sqrt(1/2*(1+sqrt(2*n +1)))))),n=0...infinity)
3. WolframAlpha hangs on calculating sum(1/(IntegerPart(exp(Pi*sqrt(19+24*n)))),n=0...infinity)
