integral from 0 to 1 of x^3(1-x)

Solution

\int_{0}^{1} x^{3} (1 - x) d x

Solution

\frac{1}{20}

+1

Decimal

0.05

Solution steps

\int_{0}^{1} x^{3} (1 - x) d x

Expand

x^{3} (1 - x) : x^{3} - x^{4}

= \int_{0}^{1} x^{3} - x^{4} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{1} x^{3} d x - \int_{0}^{1} x^{4} d x

\int_{0}^{1} x^{3} d x = \frac{1}{4}

\int_{0}^{1} x^{4} d x = \frac{1}{5}

= \frac{1}{4} - \frac{1}{5}

Simplify

\frac{1}{4} - \frac{1}{5} : \frac{1}{20}

= \frac{1}{20}
