I can write you a loop to calculate this, but i'd need more
time to work on the other one...

for x=1 to iterations%
if (x/2=int(x/2)) or (x=1) then
t=t+1/((x*2)+1)
else
t=t-1/((x*2)+1)
end if
next x
pi=4*(1-t)

That SHOULD work.  if not, fiddle it until it does.  I'll
look at the second series tonight and come up with some
finished code for you by sunday.
