integral from 0 to 20 of 1/2 x

\int_{0}^{20} \frac{1}{2} x d x

100

Solution steps

\int_{0}^{20} \frac{1}{2} x 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}^{20} x d x

Apply the Power Rule

= \frac{1}{2} [\frac{x ^{2}}{2}]_{0}^{20}

Compute the boundaries:

200

= \frac{1}{2} \cdot 200

Simplify

= 100
