What is the antiderivative of x^x?

In summary, the antiderivative of x^x is x^(x+1)/(x+1) + C, where C is a constant. The antiderivative is not simply x^(x+1) because the exponent must be one less than the original exponent in order to maintain the same function. It can be further simplified using logarithmic properties to x^x ln(x) + C, where ln(x) represents the natural logarithm of x. The constant C represents the family of functions that have the same derivative, and the antiderivative of x^x has an infinite number of solutions, each differing by a constant C. This antiderivative also has practical applications in various fields such as physics, engineering, and

The derivative of x^x is x^x(lnx+1) but what would be its antiderivative?
I don't think the answer is in elementary terms. According to someone there is a special function made just to answer this question. So what is it?

What is the antiderivative of x^x?

The antiderivative of x^x is x^(x+1)/(x+1) + C, where C is a constant.

Why is the antiderivative of x^x not simply x^(x+1)?

The antiderivative of x^x is not simply x^(x+1) because when using the power rule for integration, the exponent must be one less than the original exponent in order to maintain the same function. Therefore, the exponent of x must be (x+1), making the final antiderivative x^(x+1)/(x+1).

Can the antiderivative of x^x be simplified further?

Yes, the antiderivative of x^x can be simplified further by using logarithmic properties. It can be rewritten as x^x ln(x) + C, where ln(x) represents the natural logarithm of x.

What is the significance of the constant C in the antiderivative of x^x?

The constant C represents the family of functions that have the same derivative. In other words, the antiderivative of x^x has an infinite number of solutions, each differing by a constant C.

Can the antiderivative of x^x be used in real-life applications?

Yes, the antiderivative of x^x has applications in various fields such as physics, engineering, and finance. It can be used to model growth and decay processes, calculate areas under curves, and solve certain differential equations.
