integral of (1-y)^4

integral

(1 - y)^{4}

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

Solution steps

\int (1 - y)^{4} d y

Apply u-substitution

= \int - u^{4} d u

Take the constant out:

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

= - \int u^{4} d u

Apply the Power Rule

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

Substitute back

u = 1 - y

= - \frac{( 1 - y ) ^{5}}{5}

Add a constant to the solution

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