integral of (sqrt(4+x^2))/(x^4)

\int \frac{4 + x ^{2}}{x ^{4}} d x

- \frac{4 + x ^{2}}{3 x ^{3}} - \frac{4 + x ^{2}}{12 x} + C

Solution steps

\int \frac{4 + x ^{2}}{x ^{4}} d x

Apply Integration By Parts

= - \frac{4 + x ^{2}}{3 x ^{3}} - \int - \frac{1}{3 x ^{2} x ^{2} + 4} d x

\int - \frac{1}{3 x ^{2} x ^{2} + 4} d x = \frac{4 + x ^{2}}{12 x}

= - \frac{4 + x ^{2}}{3 x ^{3}} - \frac{4 + x ^{2}}{12 x}

Add a constant to the solution

= - \frac{4 + x ^{2}}{3 x ^{3}} - \frac{4 + x ^{2}}{12 x} + C
