integral of 1/(x^2)sqrt(1/x-1)

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

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

Solution steps

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

Apply u-substitution

: \int - u - 1 d u

= \int - u - 1 d u

Take the constant out:

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

= - \int u - 1 d u

Apply u-substitution

: \int v d v

= - \int v d v

Apply the Power Rule

: \frac{2}{3} v^{\frac{3}{2}}

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

Substitute back

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

Join

\frac{1}{x} - 1 : \frac{1 - x}{x}

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

Add a constant to the solution

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

\int - \frac{4}{sin ^{2} ( r )} d r

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

\int \frac{1}{( x - 8 ) ( 6 - x )} d x

\int \frac{1}{e ^{x} sin ^{2} ( e ^{- x} )} d x

\int 25 sec (5 x) tan (5 x) sec^{4} (5 x) d x
