integral from 0 to 1 of (-x+1)^2

Solution

\int_{0}^{1} (- x + 1)^{2} d x

Solution

\frac{1}{3}

+1

Decimal Notation

0.33333 \dots

Solution steps

\int_{0}^{1} (- x + 1)^{2} d x

Expand

(- x + 1)^{2} : x^{2} - 2 x + 1

= \int_{0}^{1} x^{2} - 2 x + 1 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^{2} d x - \int_{0}^{1} 2 x d x + \int_{0}^{1} 1 d x

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} 2 x d x = 1

\int_{0}^{1} 1 d x = 1

= \frac{1}{3} - 1 + 1

Simplify

= \frac{1}{3}
