SUMMARY
The integral of 1/(x^2+d^2)^(1/2) with respect to dx can be solved using the substitution x = d.tan(u). This method simplifies the integral, leading to the result ln { x + (x^2 + d^2)^(1/2) }. The discussion highlights the importance of choosing appropriate constants for differentiation to avoid confusion, suggesting alternatives like 'a' or 's' instead of 'd'. The step-by-step explanation clarifies the integration process and the rationale behind the substitution.
