Factorial Explosive Growth

ExponentialGrowth FactorialFunction AsymptoticAnalysis SuperExponential

Factorial growth dramatically exceeds exponential growth because repeated multiplication compounds the cumulative effect of all previous factors.

Factorial Function: Product of Natural Numbers

FactorialFunction Combinatorics DiscreteSequence ProductNotation

The factorial function, denoted by an exclamation point n!, represents the product of all positive integers up to and including n, serving as a fundamental combinatorial operation.

Factorial Recursive Formula

RecursiveFormulas FactorialFunction Sequences Iteration

The factorial recursive relation n! = n × (n-1)! transforms the explicit product definition into an iterative formula where each value depends on its predecessor.

Factorial Super Recursive Formula

RecursiveFormulas ProductNotation FactorialFunction Telescoping

The super recursive formula generalizes single-step factorial recursion (x+1)! = (x+1) × x! to arbitrary step sizes n.

Gamma Function: Continuous Factorial Extension

GammaFunction SpecialFunctions FactorialExtension AnalyticContinuation

The gamma function Γ(x) extends the factorial function from discrete integers to continuous real (and complex) numbers, representing one of mathematics’ most important special functions.

Logarithmic Transformation: Products to Sums
