integral of 2/(12-5x)

\int \frac{2}{12 - 5 x} d x

- \frac{2}{5} ln ∣ 12 - 5 x ∣ + C

Solution steps

\int \frac{2}{12 - 5 x} d x

Take the constant out:

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

= 2 \cdot \int \frac{1}{12 - 5 x} d x

Apply u-substitution

: \int - \frac{1}{5 u} d u

= 2 \cdot \int - \frac{1}{5 u} d u

Take the constant out:

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

= 2 (- \frac{1}{5} \cdot \int \frac{1}{u} d u)

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= 2 (- \frac{1}{5} ln ∣ u ∣)

Substitute back

u = 12 - 5 x

= 2 (- \frac{1}{5} ln ∣ 12 - 5 x ∣)

Simplify

2 (- \frac{1}{5} ln ∣ 12 - 5 x ∣) : - \frac{2}{5} ln ∣ 12 - 5 x ∣

= - \frac{2}{5} ln ∣ 12 - 5 x ∣

Add a constant to the solution

= - \frac{2}{5} ln ∣ 12 - 5 x ∣ + C

arccos (x)

(1 + x)^{- \frac{4}{3}}

\frac{\partial}{\partial x} (\frac{1}{ln ( \frac{y}{x} )})

\frac{s ^{2}}{( s ^{2} + 1 ) ^{2}}

ln (\frac{( x + 6 ) ^{4} e ^{5 x^{3} - 3}}{x + 2 x ^{3}})
