SUMMARY
The integral of the function (xe^x)/(sqrt[1+e^x]) can be simplified using the substitution u = sqrt(1 + e^x). This substitution transforms the integral into a more manageable form, allowing for further analysis and solution. Initial attempts using u = e^x and other methods such as trigonometric substitution and partial fractions proved ineffective. The key to solving this integral lies in recognizing the appropriate substitution that simplifies the expression significantly.
