integral from 0 to 3 of (sin(x))/x

\int_{0}^{3} \frac{sin ( x )}{x} d x

1.84865 \dots

Solution steps

\int_{0}^{3} \frac{sin ( x )}{x} d x

Use the nonelementary integral:

\int \frac{sin ( x )}{x} d x = Si (x)

= [Si (x)]_{0}^{3}

Compute the boundaries:

1.84865 \dots

= 1.84865 \dots

\int_{0}^{3} (x^{2} - 3 x + 2) d x

\int_{0}^{1} e^{13 x - 12} d x

\int_{0}^{7} e^{- 4 x} d x

\int_{0}^{\frac{π}{4}} cos (4 x) d x

\int_{0}^{π} e^{i x} d x
