SUMMARY
The integration of the function cos(x)/(1+sin^2(x))dx can be effectively solved using the method of u-substitution. Participants in the discussion emphasized that recognizing cos(x) as the derivative of sin(x) is crucial for simplifying the integral. The transformation to the format ∫(du)/(1+u^2) is a key step in solving the integral, allowing for the application of known integration techniques. By focusing on u-substitution, users can navigate the complexities of the integral more efficiently.
