integral from-2 to 1 of x+1

Solution

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

Solution

\frac{3}{2}

+1

Decimal Notation

1.5

Solution steps

\int_{- 2}^{1} 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_{- 2}^{1} x d x + \int_{- 2}^{1} 1 d x

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

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

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

Simplify

- \frac{3}{2} + 3 : \frac{3}{2}

= \frac{3}{2}
