integral of ((x^5-2x^2))/((1+x^3)^{3/2)}

\int \frac{( x ^{5} - 2 x ^{2} )}{( 1 + x ^{3} ) ^{\frac{3}{2}}} d x

\frac{2 x ^{3} + 4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}} + \frac{4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}} + C

Solution steps

\int \frac{x ^{5} - 2 x ^{2}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} d x

Expand

\frac{x ^{5} - 2 x ^{2}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} : \frac{x ^{5}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} - \frac{2 x ^{2}}{( 1 + x ^{3} ) ^{\frac{3}{2}}}

= \int \frac{x ^{5}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} - \frac{2 x ^{2}}{( 1 + x ^{3} ) ^{\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 \frac{x ^{5}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} d x - \int \frac{2 x ^{2}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} d x

\int \frac{x ^{5}}{( 1 + x ^{3} ) ^{\frac{3}{2}}} d x = \frac{2 x ^{3} + 4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}}

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

= \frac{2 x ^{3} + 4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}} - (- \frac{4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}})

Simplify

= \frac{2 x ^{3} + 4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}} + \frac{4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}}

Add a constant to the solution

= \frac{2 x ^{3} + 4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}} + \frac{4}{3 ( 1 + x ^{3} ) ^{\frac{1}{2}}} + C

f (x) = \frac{1}{x + 1}

f (x) = x^{2} + 4, (- 4, 20)

\frac{d}{d u} (2 uv)

\frac{d}{d x} (ln ∣ coth (5 x) ∣)
