integral from-2 to 1 of (x^4+x^3-2x^2+4)

\int_{- 2}^{1} (x^{4} + x^{3} - 2 x^{2} + 4) d x

\frac{177}{20}

Decimal

8.85

Solution steps

\int_{- 2}^{1} x^{4} + x^{3} - 2 x^{2} + 4 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}^{1} x^{4} d x + \int_{- 2}^{1} x^{3} d x - \int_{- 2}^{1} 2 x^{2} d x + \int_{- 2}^{1} 4 d x

\int_{- 2}^{1} x^{4} d x = \frac{33}{5}

\int_{- 2}^{1} x^{3} d x = - \frac{15}{4}

\int_{- 2}^{1} 2 x^{2} d x = 6

\int_{- 2}^{1} 4 d x = 12

= \frac{33}{5} - \frac{15}{4} - 6 + 12

Simplify

\frac{33}{5} - \frac{15}{4} - 6 + 12 : \frac{177}{20}

= \frac{177}{20}

\int_{0}^{π} z cos (n z) d z

\int_{0}^{1} 2 x^{3} (3 x^{4} + 2)^{6} d x

\int_{2}^{\infty} y^{- 3} d y

\int_{0}^{\frac{3 π}{2}} 1

\int_{- x}^{x} sin (t^{2}) d t
