integral from 6 to 7 of x^2-2x-24

\int_{6}^{7} x^{2} - 2 x - 24 d x

\frac{16}{3}

Decimal

5.33333 \dots

Solution steps

\int_{6}^{7} x^{2} - 2 x - 24 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_{6}^{7} x^{2} d x - \int_{6}^{7} 2 x d x - \int_{6}^{7} 24 d x

\int_{6}^{7} x^{2} d x = \frac{127}{3}

\int_{6}^{7} 2 x d x = 13

\int_{6}^{7} 24 d x = 24

= \frac{127}{3} - 13 - 24

Simplify

\frac{127}{3} - 13 - 24 : \frac{16}{3}

= \frac{16}{3}

\int_{1}^{2} \frac{ln ( x )}{x} d x

\int_{3}^{6} t^{2} ln (t) d t

\int_{- \frac{π}{3}}^{\frac{π}{3}} csc^{2} (x) d x

\int_{3}^{8} \frac{x}{x + 1} d x

\int_{0}^{1} 2 π x (1 - x^{2}) d x
