integral from 0 to infinity of 5/(x^2+3)

\int_{0}^{\infty} \frac{5}{x ^{2} + 3} d x

\frac{5 π}{2 3}

Decimal Notation

4.53449 \dots

Solution steps

\int_{0}^{\infty} \frac{5}{x ^{2} + 3} d x

Compute the indefinite integral:

\int \frac{5}{x ^{2} + 3} d x = \frac{5}{3} arctan (\frac{x}{3}) + C

Compute the boundaries:

\int_{0}^{\infty} \frac{5}{x ^{2} + 3} d x = \frac{5}{3} \cdot \frac{π}{2} - 0

= \frac{5}{3} \cdot \frac{π}{2} - 0

Simplify

= \frac{5 π}{2 3}

\int_{0}^{2} 2 x e^{- 3 x} d x

\int_{0}^{\frac{π}{4}} 8 sec (θ) tan (θ) d θ

\int_{0}^{π} sin^{3} (\frac{t}{2}) d t

\int_{2}^{3} 0 d x

\int_{- \frac{π}{3}}^{\frac{π}{4}} cos (θ) d θ
