integral from 1/2 to 1 of (x^{-3}-3)

\int_{\frac{1}{2}}^{1} (x^{- 3} - 3) d x

0

Solution steps

\int_{\frac{1}{2}}^{1} x^{- 3} - 3 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_{\frac{1}{2}}^{1} x^{- 3} d x - \int_{\frac{1}{2}}^{1} 3 d x

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

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

= \frac{3}{2} - \frac{3}{2}

Simplify

= 0
