integral of x^2+1/(x^3)

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

\frac{x ^{3}}{3} - \frac{1}{2 x ^{2}} + C

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int x^{2} d x = \frac{x ^{3}}{3}

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

= \frac{x ^{3}}{3} - \frac{1}{2 x ^{2}}

Add a constant to the solution

= \frac{x ^{3}}{3} - \frac{1}{2 x ^{2}} + C
