The complementary error function, denoted erfc, is defined as
which also defines erfcx, the scaled complementary error function (which can be used instead of erfc to avoid arithmetic underflow). Another form of is known as Craig's formula:
The imaginary error function, denoted erfi, is defined as
Despite the name "imaginary error function", is real when x is real.
When the error function is evaluated for arbitrary complex arguments z, the resulting complex error function is usually discussed in scaled form as the Faddeeva function:
The name "error function"
The error function is used in measurement theory (using probability and statistics), and its use in other branches of mathematics is typically unrelated to the characterization of measurement errors.
How to use the error function for some tough integral
In this video, I showed how to use the error function to compute some difficult integrals. the real gaussian error function and the imaginary error function was also used in this video. Erfi(x) is a modified version of erf(x)

the impossible integral of e^(-x^2) & the error function
The Error Function is the integral of e^(-x^2) and is closely related to the Gaussian integral. This is a non-elementary function (or you can call it an advanced function). Subscribe to @blackpenredpenfor more fun math videos.

The Gaussian Integral is a term that describes the area under a normal distribution of mean 1. This value is equal to the square root of pi. In this video, I go over the hidden circle behind this, using a bit of multivariable calculus. Hope you enjoy!

Call Stack - Knowledge you must know for debugging
#coding #programming #debugging
In this lecture, we introduce 'Call Stack', one of the core concepts of programming languages. The Call Stack is a memory structure where information related to the function is stored when it is called. The Call Stack is based on the Last In Last Out (LILO) principle, which means that the late entrants leave first. In this lecture, we take a close look at why understanding and using the Call Stack is important, and examples that can help you understand it.
In addition, we detail how the Call Stack affects the order of function calls, execution and termination, and error handling. This will help you understand the concept of Stack Frame and the range of data accessible in each function, known as scope.
Also, you'll learn about error conditions like Stack ...
