integral from 2 to infinity of 3/(x^2)

\int_{2}^{\infty} \frac{3}{x ^{2}} d x

\frac{3}{2}

Decimal

1.5

Solution steps

\int_{2}^{\infty} \frac{3}{x ^{2}} d x

Compute the indefinite integral:

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

Compute the boundaries:

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

= 0 - (- \frac{3}{2})

Simplify

= \frac{3}{2}

\int_{0}^{x} \frac{x ^{2}}{2} d x

\int_{x^{3}}^{1} 9 x^{2} y d y

\int_{0}^{π} (sin (x) - 7) d x

\int_{0}^{5} (\frac{50}{x + 5} - 5) d x

\int_{1}^{3} (x - 2)^{4} d x
