\int_{1}^{8} 4 d x

28

Solution steps

\int_{1}^{8} 4 d x

Integral of a constant:

\int a d x = a x

= [4 x]_{1}^{8}

Compute the boundaries:

28

= 28

\int_{- \infty}^{- 2} e^{x} d x

\int_{0}^{\frac{π}{2}} 2 x cos (2 x) d x

\int_{\frac{1}{2}}^{1} \frac{8}{x ^{3}} d x

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

\int_{0}^{π} sin (x) x d x
