Vedclass · Answer

(A) To evaluate the integral $I = \int \frac{x}{1+x^4} \, dx$,we can use the method of substitution.Let $u = x^2$. Then,the derivative is $du = 2x \, dx$,which implies $x \, dx = \frac{1}{2} \, du$.Substituting these into the integral,we get:$I = \int \frac{1}{1+(x^2)^2} \cdot (x \, dx) = \int \frac{1}{1+u^2} \cdot \frac{1}{2} \, du$$I = \frac{1}{2} \int \frac{1}{1+u^2} \, du$Using the standard integral formula $\int \frac{1}{1+u^2} \, du = 	an^{-1}(u) + c$,we have:$I = \frac{1}{2} 	an^{-1}(u) + c$Substituting $u = x^2$ back into the expression,we get:$I = \frac{1}{2} 	an^{-1}(x^2) + c$Thus,the correct option is $A$.
