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

\int_{0}^{π} \frac{sin ( x )}{x} d x

Si (π)

Solution steps

\int_{0}^{π} \frac{sin ( x )}{x} d x

Use the nonelementary integral:

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

= [Si (x)]_{0}^{π}

Compute the boundaries:

Si (π)

= Si (π)

f (x) = 1 - 6 x

x \to 3 - lim (\frac{3 x + 4}{x - 3})

\int sec^{7} (5 x) tan (5 x) d x

\int 3 x - 7 d x

f (x) = sin (x) + cos (x), at x = 0
