integral of 1/((a-x)^3)

integral

\frac{1}{( a - x ) ^{3}}

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

Solution steps

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

Apply u-substitution

= \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}})

Substitute back

u = a - x

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

Simplify

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

Add a constant to the solution

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