How to show a series diverges
WebSep 18, 2015 · Now to show it, you will have to make use of the fact that log ( 1 / n) becomes arbitrarily negative as n approaches infinity, and so no matter what L is, you will always find some sufficiently large n so that the absolute value of log ( 1 / n) is so big, that it cannot be within a distance, of say, ϵ = 1 from the prescribed L. WebOne of the main things a function has to do to approach a number is to start to stabilize. Take sine or cosine. We know they will never output anything greater than 1, or less than -1, we are even able to compute them for any real number. But, we know that they will always fluctuate. They don't head to infinity, and they don't converge.
