In summary, the integral of 1/x^(1+a) is equal to (x^a)/(a-1) + C, where C is the constant of integration. To solve this integral, you can use the power rule for integration, and the value of the constant of integration is arbitrary. The integral can also be simplified using algebraic manipulation, but it is not necessary. There are restrictions on the value of "a," where it cannot equal 1 and must be greater than -1 for the integral to converge.

I need help getting the integral of

1/x^(1+a)

I tried using substitution but it didnt work.
I keep getting x/a. Could someone show
me what I am doing wrong.

I take it "a" is a real constant? Substitution is not necessary. Do you know the integral of x^p (where p is a real number)? Do you see how it can be applied here?

Oh I see

now I got -(x^-a/a)

is this correct?

+ C of course ;)

FAQ: How Do You Integrate 1/x^(1+a)?

What is the integral of 1/x^(1+a)?

The integral of 1/x^(1+a) is equal to (x^a)/(a-1) + C, where C is the constant of integration.

How do you solve the integral of 1/x^(1+a)?

To solve the integral of 1/x^(1+a), you can use the power rule for integration, which states that the integral of x^n is equal to (x^(n+1))/(n+1) + C. In this case, you would need to use the power rule twice, first on the denominator to get x^(-a) and then on the resulting term to get x^(-a+1).

What is the value of the constant of integration in the integral of 1/x^(1+a)?

The value of the constant of integration in the integral of 1/x^(1+a) is arbitrary and can be represented by any constant, such as C, K, or A.

Can the integral of 1/x^(1+a) be simplified further?

Yes, the integral of 1/x^(1+a) can be simplified using algebraic manipulation. For example, you can factor out an x^a term from the numerator to get x^a(1/(x^(1+a))) = x^a/x^(1+a) = 1/x. However, this is not necessary as the original integral is already a valid solution.

Are there any restrictions on the value of "a" in the integral of 1/x^(1+a)?

Yes, there are restrictions on the value of "a" in the integral of 1/x^(1+a). Since the integral involves dividing by (a-1), the value of a cannot equal 1. Additionally, for the integral to converge, a must be greater than -1, otherwise, it will result in a divergent integral.
