integral from 1 to 4 of |t^2-t-6|

\int_{1}^{4} t^{2} - t - 6 d t

\frac{61}{6}

Decimal

10.16666 \dots

Solution steps

\int_{1}^{4} t^{2} - t - 6 d t

Eliminate Absolutes

= \int_{1}^{3} - t^{2} + t + 6 d t + \int_{3}^{4} t^{2} - t - 6 d t

\int_{1}^{3} - t^{2} + t + 6 d t = \frac{22}{3}

\int_{3}^{4} t^{2} - t - 6 d t = \frac{17}{6}

= \frac{22}{3} + \frac{17}{6}

Simplify

\frac{22}{3} + \frac{17}{6} : \frac{61}{6}

= \frac{61}{6}

\int_{0}^{2} (t^{3} + t) d t

\int_{0}^{\infty} x^{9} e^{- x} d x

\int_{1}^{2 t} u 9 + u^{2} d u

\int_{1}^{2} (6 x y^{2} - \frac{4 x}{y}) d y

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