integral of (1-x)^{-3}

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

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

Solution steps

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

Apply u-substitution

: \int - \frac{1}{u ^{3}} d u

= \int - \frac{1}{u ^{3}} d u

Take the constant out:

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

= - \int \frac{1}{u ^{3}} d u

Apply the Power Rule

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

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

Substitute back

u = 1 - x

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

Simplify

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

Add a constant to the solution

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

\int x^{3} 1 - x^{4} d x

\int (x + 3) d x

\frac{2 ^{2}}{s ( s + 2 ) ^{2}}

\int \frac{1}{x ^{2} - 6 x + 8} d x

\int cos (x) cos (2 x) d x
