integral from-2 to-1 of 1

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

1

Solution steps

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

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{- 2}^{- 1}

Simplify

= [x]_{- 2}^{- 1}

Compute the boundaries:

1

= 1

\int_{- 4}^{4} ∣ x - 2 ∣ d x

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

\int_{0}^{5} (x - 3) (x - 1) d x

\int_{- 2}^{2} 2 - ∣ x ∣ d x

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