integral from 2 to infinity of 7/(x^2)

\int_{2}^{\infty} \frac{7}{x ^{2}} d x

\frac{7}{2}

Decimal

3.5

Solution steps

\int_{2}^{\infty} \frac{7}{x ^{2}} d x

Compute the indefinite integral:

\int \frac{7}{x ^{2}} d x = - \frac{7}{x} + C

Compute the boundaries:

\int_{2}^{\infty} \frac{7}{x ^{2}} d x = 0 - (- \frac{7}{2})

= 0 - (- \frac{7}{2})

Simplify

= \frac{7}{2}

\int_{0}^{2} ln (x^{2} + 1) x d x

\int_{4.9}^{5.1} x^{2} (5 x - 24.5) d x

\int_{- 1}^{5} x^{3} d x

\int_{0}^{s i n (y)} 1 + cos (y) d y

\int_{0}^{\frac{π}{4}} 7 sec^{2} (t) d t
