Homework Help Overview

The discussion revolves around the integral of the expression \((\sqrt{x} + \frac{1}{\sqrt{x}})^2\), which falls under the subject area of calculus, specifically focusing on integration techniques.

Discussion Character

  • Exploratory, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss simplifying the expression before integrating, with some suggesting the breakdown of the integral into manageable parts. There are mentions of technical details regarding logarithmic integration and the implications of absolute values in the context of the integral.

Discussion Status

Some participants express agreement with the initial approach to the integral, while others highlight important technicalities that should be considered, such as the inclusion of the constant of integration and the treatment of absolute values. The discussion appears to be productive, with various aspects of the integral being explored.

Contextual Notes

There are references to potential assumptions about the variable \(x\) and its implications on the final answer, particularly regarding odd powers and parametric equations, which may affect the interpretation of the integral.

[SOLVED] Can I do this? (integral)

\int(\sqrt{x}+\frac{1}{\sqrt{x}})^2dx sum of a product ... simplify

\int(x+2+\frac{1}{x})dx integrating ...

\frac{1}{2}x^2+2x+\ln{x}

Looks correct to me.
 
Looks ok to me.
 
damn i love math :-] idk why i didn't think about doing it earlier.
 
Just some technicalities, \int \frac{dx}{x} = ln |x|. and \sqrt{x}^2=|x| don't think it affects anything really but if x was to be an odd power in the final answer I think it would need to be given as a parametric equation.
 
And you certainly should have "+ C"!
