integral from 0 to pi of 27sin(x)

\int_{0}^{π} 27 sin (x) d x

54

Solution steps

\int_{0}^{π} 27 sin (x) d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 27 \cdot \int_{0}^{π} sin (x) d x

Use the common integral:

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

= 27 [- cos (x)]_{0}^{π}

Compute the boundaries:

2

= 27 \cdot 2

Simplify

= 54
