integral from-2 to 3 of (x+4)-(x^2-2)

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

\frac{125}{6}

Decimal

20.83333 \dots

Solution steps

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

Simplify

= \int_{- 2}^{3} - x^{2} + x + 6 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_{- 2}^{3} x^{2} d x + \int_{- 2}^{3} x d x + \int_{- 2}^{3} 6 d x

\int_{- 2}^{3} x^{2} d x = \frac{35}{3}

\int_{- 2}^{3} x d x = \frac{5}{2}

\int_{- 2}^{3} 6 d x = 30

= - \frac{35}{3} + \frac{5}{2} + 30

Simplify

- \frac{35}{3} + \frac{5}{2} + 30 : \frac{125}{6}

= \frac{125}{6}

\int_{0}^{6} e^{x^{2}} d x

\int_{\frac{π}{6}}^{\frac{π}{2}} 2 sin (x) d x

\int_{0}^{1} \frac{1}{1 - x ^{4}} d x

\int_{0}^{30} 1.0 3^{x} d x

\int_{0}^{2 π} - 3 sin^{2} (t) d t
