integral of ((1-x^2)^{3/2})/(x^6)

\int \frac{( 1 - x ^{2} ) ^{\frac{3}{2}}}{x ^{6}} d x

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

Solution steps

\int \frac{( 1 - x ^{2} ) ^{\frac{3}{2}}}{x ^{6}} d x

Apply Trigonometric Substitution

: \int \frac{cos ^{4} ( u )}{sin ^{6} ( u )} d u

= \int \frac{cos ^{4} ( u )}{sin ^{6} ( u )} d u

Rewrite using trig identities

= \int cot^{4} (u) csc^{2} (u) d u

Apply u-substitution

: \int - v^{4} d v

= \int - v^{4} d v

Take the constant out:

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

= - \int v^{4} d v

Apply the Power Rule

: \frac{v ^{5}}{5}

= - \frac{v ^{5}}{5}

Substitute back

= - \frac{cot ^{5} ( arcsin ( x ) )}{5}

Simplify

- \frac{cot ^{5} ( arcsin ( x ) )}{5} : - \frac{( 1 - x ^{2} ) ^{\frac{5}{2}}}{5 x ^{5}}

= - \frac{( 1 - x ^{2} ) ^{\frac{5}{2}}}{5 x ^{5}}

Add a constant to the solution

= - \frac{( 1 - x ^{2} ) ^{\frac{5}{2}}}{5 x ^{5}} + C

\int \frac{x}{1 + 10 x ^{2}} d x

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

\int \frac{6}{2 x - 1} d x

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

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