integral from 0 to 1 of (u+5)(u-6)

\int_{0}^{1} (u + 5) (u - 6) d u

- \frac{181}{6}

Decimal Notation

- 30.16666 \dots

Solution steps

\int_{0}^{1} (u + 5) (u - 6) d u

Expand

(u + 5) (u - 6) : u^{2} - u - 30

= \int_{0}^{1} u^{2} - u - 30 d u

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} u^{2} d u - \int_{0}^{1} u d u - \int_{0}^{1} 30 d u

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

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

\int_{0}^{1} 30 d u = 30

= \frac{1}{3} - \frac{1}{2} - 30

Simplify

\frac{1}{3} - \frac{1}{2} - 30 : - \frac{181}{6}

= - \frac{181}{6}

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

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

\int_{0}^{x^{2}} 3 sin (x) d x

\int_{0}^{\frac{π}{2}} 2 sin (x) d x

\int_{- \infty}^{- 1} e^{x} d x
