Hello everyone, I'm starting to study sequences. I'm on Stewart's Calculus textbook (single variable, 7th edition, for those who have it, on p. 693). Now, I'm at the part where the limit laws are "transferred" to sequences. (I'm sorry. I do not know how to code. I hope this is clear to you.) lim as n->infinity of anp=[lim as n->infinity of an]p IF p>0 AND an>0 Why do they add the IF p>0 AND an>0? I do not see why the formula would be wrong without that.
