integral from 1 to 8 of 5/t

\int_{1}^{8} \frac{5}{t} d t

15 ln (2)

Decimal Notation

10.39720 \dots

Solution steps

\int_{1}^{8} \frac{5}{t} d t

Take the constant out:

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

= 5 \cdot \int_{1}^{8} \frac{1}{t} d t

Use the common integral:

\int \frac{1}{t} d t = ln (∣ t ∣)

= 5 [ln ∣ t ∣]_{1}^{8}

Compute the boundaries:

3 ln (2)

= 5 \cdot 3 ln (2)

Simplify

= 15 ln (2)

\int_{- 4}^{2} 2 x d x

\int_{x}^{y} \frac{1}{x} d x

\int_{1}^{16} (x^{- \frac{3}{4}}) d x

\int_{- 2}^{3} (x^{2} - 2 x + 1) d x

\int_{0}^{\frac{5 π}{6}} 4 tan (\frac{x}{5}) d x
