integral from 0 to 4 of-x/2

\int_{0}^{4} - \frac{x}{2} d x

- 4

Solution steps

\int_{0}^{4} - \frac{x}{2} d x

Take the constant out:

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

= - \frac{1}{2} \cdot \int_{0}^{4} x d x

Apply the Power Rule

: [\frac{x ^{2}}{2}]_{0}^{4}

= - \frac{1}{2} [\frac{x ^{2}}{2}]_{0}^{4}

Compute the boundaries:

8

= - \frac{1}{2} \cdot 8

Simplify

= - 4

\int_{- 2}^{- 1} - x - 1 d x

\int_{1}^{2} (y - \frac{1}{y ^{2}}) d y

\int_{1}^{x^{2}} 1 + t d t

\int_{2}^{x^{3}} ln (x) d x

\int_{0}^{2} \frac{1}{( x + 2 ) ^{4}} d x
