integral from 0 to 2 of 1/4 (x^2-7)

\int_{0}^{2} \frac{1}{4} (x^{2} - 7) d x

- \frac{17}{6}

Decimal Notation

- 2.83333 \dots

Solution steps

\int_{0}^{2} \frac{1}{4} (x^{2} - 7) d x

Take the constant out:

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

= \frac{1}{4} \cdot \int_{0}^{2} x^{2} - 7 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

= \frac{1}{4} (\int_{0}^{2} x^{2} d x - \int_{0}^{2} 7 d x)

\int_{0}^{2} x^{2} d x = \frac{8}{3}

\int_{0}^{2} 7 d x = 14

= \frac{1}{4} (\frac{8}{3} - 14)

Simplify

\frac{1}{4} (\frac{8}{3} - 14) : - \frac{17}{6}

= - \frac{17}{6}

\int_{0}^{1} \frac{1}{x} sin (\frac{1}{x}) d x

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

\int_{- 10}^{10} t d t

\int_{0}^{π} (sin (x) - 8 x^{3}) d x

\int_{x}^{1} 24 x (1 - y) d y
