integral from 0 to pi of 4cos(x)

\int_{0}^{π} 4 cos (x) d x

0

Solution steps

\int_{0}^{π} 4 cos (x) d x

Take the constant out:

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

= 4 \cdot \int_{0}^{π} cos (x) d x

Use the common integral:

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

= 4 [sin (x)]_{0}^{π}

Compute the boundaries:

0

= 4 \cdot 0

Simplify

= 0

\int_{x - 1}^{2 x + 6} x y d y

\int_{1}^{3} (t^{2} - t - 6) d t

\int_{4}^{6} \frac{1}{x x ^{2} - 4} d x

\int_{4}^{7} (2 x^{2} - x) d x

\int_{0}^{6} 80 x e^{\frac{- x}{10}} d x
