Explanation: Let x = tanθ ⇒ dx = sec2θ dθ & θ = tan−1(x) ∴ ∫ 1 x2 +1 dx. = ∫ 1 tan2θ +1 sec2θ dθ.
The integral of \(\frac{1}{x^2 + 1}\) with respect to \(x\) is \(\arctan(x) + C\), where \(C\) is the constant of integration. This integral is a standard result in calculus, derived from the derivative of the arctan (or inverse tangent) function.
