SUMMARY
The integrals \(\int\frac{dx}{1+x^{2}}\) and \(\int\frac{1}{1+x^{2}}dx\) are equivalent expressions representing the same mathematical concept. Both integrals yield the same result, as the presence of the differential \(dx\) in the numerator does not alter the value of the integral. This equivalence is established through the fundamental properties of integrals in calculus.
