Questions & Answers

Q: What is the formula for the error function?

The error function, ER f of X, is defined as 2 over square root of pi times the integral from 0 to X of e to the negative T squared DT.

Q: How can the integral of the error function be obtained?

The integral of the error function can be obtained by differentiating the function, resulting in x times ER f of X.

Q: What is the second integral in the solution?

The second integral, known as the minor, is still an integral with the equation 2 over the square root of pi times e to the negative x squared DX.

Q: How is the final result derived?

By using the integration by parts method, the initial integral is modified, resulting in two parts: x times ER f of X and the minor integral.
