integral from 0 to 1 of (2x)/((x^2+5)^3)

\int_{0}^{1} \frac{2 x}{( x ^{2} + 5 ) ^{3}} d x

\frac{11}{1800}

Decimal

0.00611 \dots

Solution steps

\int_{0}^{1} \frac{2 x}{( x ^{2} + 5 ) ^{3}} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \int_{0}^{1} \frac{x}{( x ^{2} + 5 ) ^{3}} d x

Apply u-substitution

: \int_{5}^{6} \frac{1}{2 u ^{3}} d u

= 2 \cdot \int_{5}^{6} \frac{1}{2 u ^{3}} d u

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 2 \cdot \frac{1}{2} \cdot \int_{5}^{6} \frac{1}{u ^{3}} d u

Apply the Power Rule

: [- \frac{1}{2 u ^{2}}]_{5}^{6}

= 2 \cdot \frac{1}{2} [- \frac{1}{2 u ^{2}}]_{5}^{6}

Simplify

2 \cdot \frac{1}{2} [- \frac{1}{2 u ^{2}}]_{5}^{6} : [- \frac{1}{2 u ^{2}}]_{5}^{6}

= [- \frac{1}{2 u ^{2}}]_{5}^{6}

Compute the boundaries:

\frac{11}{1800}

= \frac{11}{1800}

\int_{- 2}^{3} ∣ 4 x (x - 1) ∣ d x

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

\int_{0}^{1} e^{y^{2}} d y

\int_{2}^{\infty} x^{2} ln (x) d x

\int_{- 2}^{1} 1 d x
