The error function, commonly denoted erf, is the function involved in integrating the normal distribution.

Erf is a college-level concept that would be first encountered in a probability and statistics course.

Prerequisites

Integral: An integral is a mathematical object that can be interpreted as an area or a generalization of area. Integrals and derivatives are the fundamental objects of calculus.
Normal Distribution: The normal distribution is a probability distribution associated with many sets of real-world data. Due to the shape of this distribution, it is also famously called the "bell curve."
