Understanding the Integration of x2/x1^2

Integration, a fundamental concept in calculus, often appears in a variety of contexts from engineering to physics. This article aims to provide a clear and detailed guide on how to integrate the expression #x222B;#x2212;#x221E;∞ xx2 dx[/itex].

Step-by-Step Integration Process

The expression we need to integrate is given by #x222B;x1x2(x1)2dx1[/itex], which can be simplified to #x222B;x1x1x12dx1[/itex].

By breaking it down, we can further simplify it to:

#x222B;x11x12dx1[/itex] and #x222B;x11x1dx1[/itex].

Substitution Method

To integrate the expression more easily, we use a substitution method. Let’s substitute u x1[/itex], which implies du dx1[/itex].

Substituting u x1[/itex] into the integral, we get:

#x222B;x1u1(u)2du[/itex]

This can be further broken down into:

#x222B;x1(1u1u2) du[/itex]

Evaluating this integral, we apply the standard integral formulas:

lnu - 1u C[/itex]

Undoing the substitution u x1[/itex], we get:

lnx1 - 1x1 C[/itex]

Conclusion and Verification

To verify the correctness of the integration, one can substitute the limits of integration (if given) or differentiate the result to check if it matches the original integrand. This method ensures the process is both accurate and thorough.

Common Integration Techniques

The integration of xx2[/itex] and 1x2[/itex] can also be done through the following methods:

Substitution Method: As shown above, letting u x1[/itex] simplifies the integral.

Partial Fractions: While not necessary for this specific integral, this method can be useful for more complex integrals involving rational functions.

Integration by Parts: For integrals involving products of functions, this method can be applied but is not necessary here.
