User is interested in learning about calculus and integration techniques.To integrate (\frac{{\text{int}}(x+1)}{{(x^2+1)^2(x^2)}}) using partial fractions, first express the integrand as a sum of partial fractions. The integrand can be rewritten as (\frac{A}{x} + \frac{B}{x^2} + \frac{Cx+D}{x^2+1} + \frac{Ex+F}{(x^2+1)^2}). Then, find the values of (A), (B), (C), (D), (E), and (F) by comparing the coefficients of like terms on both sides of the equation. Once you have the values, integrate each term separately.
