umm..ive tried ratio test...but it doesn't seem to be workin properly coz the fraction is sooooooo huge lol....any good idea man?
can you finish off? Bobak
actually..im worried about 2 and 3....i actually used lim test...like lim ak =0 to test its convergency for question 1....but ur way is nice anyway
