integral from 1 to 3 of (1/x)

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

ln (3)

Decimal

1.09861 \dots

Solution steps

\int_{1}^{3} \frac{1}{x} d x

Use the common integral:

\int \frac{1}{x} d x = ln (∣ x ∣)

= [ln ∣ x ∣]_{1}^{3}

Compute the boundaries:

ln (3)

= ln (3)

\int (2 x^{2} + x) e^{3 x} d x

x \to 0 lim (\frac{x ^{2} - 3 x}{x})

f (x) = \frac{1}{( x - 1 ) ^{2}}, at x = 0

\int 2 π x d x

y = x^{2} - 3
