integral from 0 to 1 of x^2+x+1

Solution

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

Solution

\frac{11}{6}

+1

Decimal

1.83333 \dots

Solution steps

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

\int_{0}^{1} x^{2} d x = \frac{1}{3}

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

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

= \frac{1}{3} + \frac{1}{2} + 1

Simplify

\frac{1}{3} + \frac{1}{2} + 1 : \frac{11}{6}

= \frac{11}{6}
