integral from 0 to 2 of (x^3+x^2+x+1)

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

\frac{32}{3}

Decimal Notation

10.66666 \dots

Solution steps

\int_{0}^{2} x^{3} + x^{2} + x + 1 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_{0}^{2} x^{3} d x + \int_{0}^{2} x^{2} d x + \int_{0}^{2} x d x + \int_{0}^{2} 1 d x

\int_{0}^{2} x^{3} d x = 4

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

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

\int_{0}^{2} 1 d x = 2

= 4 + \frac{8}{3} + 2 + 2

Simplify

4 + \frac{8}{3} + 2 + 2 : \frac{32}{3}

= \frac{32}{3}

\int_{1}^{\infty} e^{- 5 n}

\int_{0.5}^{1.5} 0.5 x d x

\int_{1}^{3} (3 x^{2} - 5 x + 2) d x

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

\int_{1}^{2} g (x) d x
