integral from 1 to infinity of 9/(x^3)

\int_{1}^{\infty} \frac{9}{x ^{3}} d x

\frac{9}{2}

Decimal

4.5

Solution steps

\int_{1}^{\infty} \frac{9}{x ^{3}} d x

Compute the indefinite integral:

\int \frac{9}{x ^{3}} d x = - \frac{9}{2 x ^{2}} + C

Compute the boundaries:

\int_{1}^{\infty} \frac{9}{x ^{3}} d x = 0 - (- \frac{9}{2})

= 0 - (- \frac{9}{2})

Simplify

= \frac{9}{2}
