This mathematical expression represents an infinite series where each term is 1 divided by n cubed (n^3), starting from n = 1 and going up to infinity (∞).
An infinite series is a series that continues indefinitely with an infinite number of terms.
Convergence refers to when an infinite series approaches a finite value as more terms are added.
Divergence refers to when an infinite series does not approach a finite value as more terms are added.
