integral from 0 to 3 of-x

\int_{0}^{3} - x d x

- \frac{9}{2}

Decimal

- 4.5

Solution steps

\int_{0}^{3} - x d x

Take the constant out:

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

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

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{0}^{3}

= - [\frac{x ^{2}}{2}]_{0}^{3}

Compute the boundaries:

\frac{9}{2}

= - \frac{9}{2}

\int_{- 1}^{2} x^{- 3} d x

\int_{- 1}^{1} π (1 - y^{2})^{2} d y

\int_{0}^{4} 2 y d y

\int_{- 1}^{1} \frac{1}{( 3 + 2 x ) ^{3}} d x

\int_{0}^{2} (2 x - 3) (4 x^{2} + 5) d x
