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

\int \frac{( x ^{3} + 3 )}{x ^{2}} d x

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

Solution steps

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

Expand

\frac{x ^{3} + 3}{x ^{2}} : x + \frac{3}{x ^{2}}

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

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

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

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

Add a constant to the solution

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

\frac{\partial ^{2}}{\partial x \partial y} (x^{2} - e^{y^{2}})

\int_{0}^{y^{3}} x e^{\frac{- x}{y}} d x

\int - 2 - \frac{2}{x} d x

\frac{d y}{d x} = \frac{2 x ^{2}}{y}

\frac{d}{d x} (2 x^{\frac{2}{3}})
