Math Problem Statement
is this statement true
Solution
Yes, the statement is true.
This is a Big-O notation analysis of the factorial function , and it aligns with Stirling's approximation, which estimates the growth of as becomes large. The approximation of is:
For asymptotic behavior, we focus on the dominant term . Thus, the factorial grows at a rate very close to this expression, with additional terms being lower order.
The inequality:
is an expression of the Big-O notation, where is some constant, and means that does not grow faster than some constant multiple of .
