Recognize Problem Complexity: Recognize that the integral of xx with respect to x is not an elementary function and cannot be expressed in terms of elementary functions.
Use Sophomore's Dream Function: Since the integral cannot be expressed in terms of elementary functions, we cannot find a closed-form solution. However, we can express the integral using a special function known as the Sophomore's dream function, which is not commonly used in elementary calculus.
Define Sophomore's Dream Function: The Sophomore's dream function is defined as the integral of x raised to the x power, but it does not have a simple expression. It is usually denoted as extint(xxextdx) and is a known function without a simple antiderivative.
Conclude with Special Function: Since we cannot find a simple antiderivative, we conclude that the integral of xx with respect to x is not expressible in terms of elementary functions and can only be represented using the special function notation or numerical methods.
