integral from-2 to 1 of pi

\int_{- 2}^{1} π d x

3 π

Decimal Notation

9.42477 \dots

Solution steps

\int_{- 2}^{1} π d x

Integral of a constant:

\int a d x = a x

= [π x]_{- 2}^{1}

Compute the boundaries:

3 π

= 3 π

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

\int_{- π}^{π} x cos^{3} (x) d x

\int_{1}^{2} 8 x e^{x^{2} + 2} d x

\int_{0}^{x} sin (t^{2}) cos (t^{2}) d t

\int_{0}^{5} ∣ 3 x - 8 ∣ d x
