integral from 0 to pi of 4sin(t)

\int_{0}^{π} 4 sin (t) d t

8

Solution steps

\int_{0}^{π} 4 sin (t) d t

Take the constant out:

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

= 4 \cdot \int_{0}^{π} sin (t) d t

Use the common integral:

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

= 4 [- cos (t)]_{0}^{π}

Compute the boundaries:

2

= 4 \cdot 2

Simplify

= 8

\int_{0}^{l n (3)} x^{2} e^{3 x} d x

\int_{1}^{\infty} \frac{8}{x ^{3}} d x

\int_{0}^{1} (\frac{cos ( x ) - 1}{x}) d x

\int_{0}^{1} cos^{4} (x) d x

\int_{5}^{7} 4 x d x
