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

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

\frac{π}{4} - \frac{1}{2}

Decimal Notation

0.28539 \dots

Solution steps

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

\int_{0}^{1} 2 x - x^{2} d x = \frac{π}{4}

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

= \frac{π}{4} - \frac{1}{2}

\int_{2 x}^{x + 5} e^{t^{2} + 1} d t

\int_{0}^{2 π} cos^{7} (x) d x

\int_{1}^{1.5} \frac{3}{2 x ^{2}} d x

\int_{1}^{5} 2 \cdot x d x

\int_{3}^{x} sec (t) tan (t) d t
