integral from pi/6 to pi/4 of sin(x)

\int_{\frac{π}{6}}^{\frac{π}{4}} sin (x) d x

- \frac{1}{2} + \frac{3}{2}

Decimal

0.15891 \dots

Solution steps

\int_{\frac{π}{6}}^{\frac{π}{4}} sin (x) d x

Use the common integral:

\int sin (x) d x = - cos (x)

= [- cos (x)]_{\frac{π}{6}}^{\frac{π}{4}}

Compute the boundaries:

- \frac{1}{2} + \frac{3}{2}

= - \frac{1}{2} + \frac{3}{2}
