integral from 1 to 2 of (4-x)

Solution

\int_{1}^{2} (4 - x) d x

Solution

\frac{5}{2}

+1

Decimal Notation

2.5

Solution steps

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

\int_{1}^{2} 4 d x = 4

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

= 4 - \frac{3}{2}

Simplify

4 - \frac{3}{2} : \frac{5}{2}

= \frac{5}{2}
