SUMMARY

The integral \(\int \frac{u}{5u+11} \, du\) can be effectively solved using the substitution method. By substituting \(x = 5u + 11\), the differential transforms to \(du = \frac{dx}{5}\). This substitution simplifies the integral, making the denominator manageable and allowing for straightforward integration. The final result will involve substituting back to express the solution in terms of \(u\).

Homework Statement


how do you integrate this one?what method do I have to use?
[tex]\int\left\left[(u/\left(5u+11\right)\right][/tex]

Can I assume that you really mean
[itex]\int\left\left[(u/\left(5u+11\right)\right]du[/itex]?
Integrals don't make much sense without the differential! (And I want to be certain that you mean u as the variable of integration!)

Have you considered the substitution x= 5u+ 11? (And having that "du" in the original integral will remind you that you need to use du= dx/5.) That will make the denominator very easy! Of course, u= (x-11)/5 but that's in the numerator and is no problem.
