integral from 1 to 2 of (5x-1)

Solution

\int_{1}^{2} (5 x - 1) d x

Solution

\frac{13}{2}

+1

Decimal Notation

6.5

Solution steps

\int_{1}^{2} 5 x - 1 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} 5 x d x - \int_{1}^{2} 1 d x

\int_{1}^{2} 5 x d x = \frac{15}{2}

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

= \frac{15}{2} - 1

Simplify

\frac{15}{2} - 1 : \frac{13}{2}

= \frac{13}{2}
