integral of (8s^3)/(sqrt(5-s^4))

\int \frac{8 s ^{3}}{5 - s ^{4}} d s

- 4 5 - s^{4} + C

Solution steps

\int \frac{8 s ^{3}}{5 - s ^{4}} d s

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 8 \cdot \int \frac{s ^{3}}{5 - s ^{4}} d s

Apply u-substitution

: \int - \frac{1}{4 u} d u

= 8 \cdot \int - \frac{1}{4 u} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 8 (- \frac{1}{4} \cdot \int \frac{1}{u} d u)

Apply the Power Rule

: 2 u^{\frac{1}{2}}

= 8 (- \frac{1}{4} \cdot 2 u^{\frac{1}{2}})

Substitute back

u = 5 - s^{4}

= 8 (- \frac{1}{4} \cdot 2 (5 - s^{4})^{\frac{1}{2}})

Simplify

8 (- \frac{1}{4} \cdot 2 (5 - s^{4})^{\frac{1}{2}}) : - 4 5 - s^{4}

= - 4 5 - s^{4}

Add a constant to the solution

= - 4 5 - s^{4} + C

\int - \frac{e ^{2 x}}{6 + e ^{x}} d x

\int (x^{2} - 2) sin (2 x) d x

\int 4 e^{3 l n (x)} d x

\int \frac{1}{1 - 0.4 x} d x

\int - \frac{32 x}{4 x ^{2} + 1} d x
