integral from pi to infinity of 4/(x^2)

\int_{π}^{\infty} \frac{4}{x ^{2}} d x

\frac{4}{π}

Decimal Notation

1.27323 \dots

Solution steps

\int_{π}^{\infty} \frac{4}{x ^{2}} d x

Compute the indefinite integral:

\int \frac{4}{x ^{2}} d x = - \frac{4}{x} + C

Compute the boundaries:

\int_{π}^{\infty} \frac{4}{x ^{2}} d x = 0 - (- \frac{4}{π})

= 0 - (- \frac{4}{π})

Simplify

= \frac{4}{π}

y^{^{''}} + 2 y^{^{'}} + y = (3 x + 4) e^{3 x}

f (x) = x^{5} - x^{3} + 3

y = x^{4} + 9 e^{x}, (0, 9)

9 x e^{- k x}

y = 4 - x^{2}, y = 14 - 7 x
