integral of (x^4-5sqrt(x))/(x^2)

\int \frac{x ^{4} - 5 x}{x ^{2}} d x

\frac{x ^{3}}{3} + \frac{10}{x} + C

Solution steps

\int \frac{x ^{4} - 5 x}{x ^{2}} d x

Expand

\frac{x ^{4} - 5 x}{x ^{2}} : x^{2} - \frac{5}{x ^{\frac{3}{2}}}

= \int x^{2} - \frac{5}{x ^{\frac{3}{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^{2} d x - \int \frac{5}{x ^{\frac{3}{2}}} d x

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

\int \frac{5}{x ^{\frac{3}{2}}} d x = - \frac{10}{x}

= \frac{x ^{3}}{3} - (- \frac{10}{x})

Simplify

= \frac{x ^{3}}{3} + \frac{10}{x}

Add a constant to the solution

= \frac{x ^{3}}{3} + \frac{10}{x} + C

x \to 0 lim (\frac{- 3}{x ^{2}})

\int ln (x^{- 1}) d x

\int \frac{11 x ^{3}}{7 + x ^{2}} d x

\frac{d}{d x} (\frac{1}{( cos ( x ) ) ^{2}})

\frac{d}{d x} ((1 + e^{- x})^{- 1})
