11.4 Infinite Sequences & Series
Question #3 (Medium): Limit Comparison Test
Limit comparison test states that for series with positive termand ∑ , if for a
finite number , then both series converge or both series diverge.
So set a similar series functio, and set the ratio and see what happens as
If the ratio becomes a fine number, then given the information known abou, conclusion can be
made about the original series function as to whether it is convergent or divergent.
Using the limit comparison test, determine
