integral from 1 to 3 of (sin(x))/x

\int_{1}^{3} \frac{sin ( x )}{x} d x

0.9025694576

Solution steps

\int_{1}^{3} \frac{sin ( x )}{x} d x

Use the nonelementary integral:

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

= [Si (x)]_{1}^{3}

Compute the boundaries:

0.9025694576

= 0.9025694576

\int_{0}^{1} \frac{18}{x ^{2} - 9} d x

\int_{- 1}^{2} 4 x^{3} + x^{- 1} d x

\int_{2}^{1} [2 f (s) + 5 g (s)] d s

\int_{- 3}^{- 1} - 3 \frac{x ^{2}}{5} + \frac{x}{5} + 6 d x

\int_{0}^{36} \frac{9}{36 - x} d x
