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

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

\frac{ln ^{2} ( 5 ) ln ( 3 )}{2}

Decimal

1.42286 \dots

Solution steps

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

Take the constant out:

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

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

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= \frac{ln ^{2} ( 5 )}{2} [ln ∣ x ∣]_{1}^{3}

Compute the boundaries:

ln (3)

= \frac{ln ^{2} ( 5 )}{2} ln (3)

Simplify

= \frac{ln ^{2} ( 5 ) ln ( 3 )}{2}

\int_{0}^{1} \frac{cos ( x )}{x ^{2}} d x

\int_{0}^{1} 5 x 5^{x} d x

\int_{0}^{4} (x + 1) - \frac{x}{2} d x

\int_{0}^{x} t (t - sin (t)) d t

\int_{0}^{4} x (x^{2} - 1) d x
