integral from-2 to 0 of 1

\int_{- 2}^{0} 1

2

Solution steps

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

Integral of a constant:

\int a d x = a x

= [1 \cdot x]_{- 2}^{0}

Simplify

= [x]_{- 2}^{0}

Compute the boundaries:

2

= 2

\int_{- 1}^{6} ∣ x ∣ d x

\int_{0}^{3} 5 x^{2} d x

\int_{0}^{1} (x^{2} - 4 x + 8) d x

\int_{0}^{2} 5 - x^{2} d x

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