integral from 0.5 to 1.5 of x/2

\int_{0.5}^{1.5} \frac{x}{2} d x

0.5

Solution steps

\int_{0.5}^{1.5} \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_{0.5}^{1.5} x d x

Apply the Power Rule

= \frac{1}{2} [\frac{x ^{2}}{2}]_{0.5}^{1.5}

Simplify

= 0.5 [0.5 x^{2}]_{0.5}^{1.5}

Compute the boundaries:

1

= 0.5 \cdot 1

Simplify

= 0.5
