integral from 1 to 2 of k-x

Solution

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

Solution

k - \frac{3}{2}

Solution steps

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

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

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

\int_{1}^{2} k d x = k

\int_{1}^{2} x d x = \frac{3}{2}

= k - \frac{3}{2}
