integral of 1/(5(2x-1))

\int \frac{1}{5 ( 2 x - 1 )} d x

\frac{1}{10} ln ∣ 2 x - 1 ∣ + C

Solution steps

\int \frac{1}{5 ( 2 x - 1 )} d x

Take the constant out:

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

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

Apply u-substitution

: \int \frac{1}{2 u} d u

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

Take the constant out:

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

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

Use the common integral:

\int \frac{1}{u} d u = ln (∣ u ∣)

= \frac{1}{5} \cdot \frac{1}{2} ln ∣ u ∣

Substitute back

u = 2 x - 1

= \frac{1}{5} \cdot \frac{1}{2} ln ∣ 2 x - 1 ∣

Simplify

\frac{1}{5} \cdot \frac{1}{2} ln ∣ 2 x - 1 ∣ : \frac{1}{10} ln ∣ 2 x - 1 ∣

= \frac{1}{10} ln ∣ 2 x - 1 ∣

Add a constant to the solution

= \frac{1}{10} ln ∣ 2 x - 1 ∣ + C

f (x) = x x

x \cdot cos (x), 1

x \to 3 lim (\frac{x ^{2} - 9}{3})

y = 11 - 6 e^{x}, (0, 5)

x \to 0 lim (\frac{ln ( x )}{x - 1})
