integral from-2 to 1 of 1

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

3

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:

3

= 3

\int_{1}^{4} 2 x + \frac{1}{x ^{2}} d x

\int_{0}^{t} sin (x) cos (t - x) d x

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

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

\int_{1}^{3} \frac{x}{( x ^{2} + 4 ) ^{3}} d x
