integral from 1 to 2 of x/y

\int_{1}^{2} \frac{x}{y} d y

x ln (2)

Solution steps

\int_{1}^{2} \frac{x}{y} d y

Take the constant out:

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

= x \cdot \int_{1}^{2} \frac{1}{y} d y

Use the common integral:

\int \frac{1}{y} d y = ln (∣ y ∣)

= x [ln ∣ y ∣]_{1}^{2}

Compute the boundaries:

ln (2)

= x ln (2)

\int_{0}^{1} 9 ln (x) d x

\int_{- 6}^{- 1} - x^{2} - 7 x - 6 d x

\int_{- \frac{π}{3}}^{\frac{π}{2}} cos (2 x) d x

\int_{0}^{2} (2 x - 1)^{9} d x

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